Lesson Overview
Level: 1 — Foundation Unit: 3 — Referring to Yourself and Others Lesson: 6 of 7 Estimated Time: 60–75 minutes for initial study, plus daily practice
What this lesson covers:
- How Spanish adjectives change form to agree with the noun they modify (gender and number)
- The four forms of standard adjectives: masculine singular, feminine singular, masculine plural, feminine plural
- Adjectives that have only two forms (no gender distinction): the invariable adjectives
- The oral substitution drill: El hombre fiel → La mujer fiel → Los hombres fieles → Las mujeres fieles
- The core ministry adjective set: fiel, salvo, nuevo, santo, eterno, perdido, redimido
- Placement rules: adjectives before vs. after nouns
- Agreement in predicative position: El hombre es fiel vs. La mujer es fiel
Prerequisites: Lesson 5 (Nouns, Articles, and Gender) must be complete. Adjective agreement builds directly on noun gender knowledge. If the 16 core nouns and their genders are not automatic, complete that review before starting this lesson.
Why Adjective Agreement Matters for Interpreters
In English, adjectives never change: the faithful man, the faithful woman, the faithful men, the faithful women. The word faithful stays the same regardless of what it describes.
In Spanish, adjectives agree with the noun in both gender and number. Fiel can be fiel (singular) or fieles (plural), but a standard adjective like salvo has four forms: salvo, salva, salvos, salvas. When the noun changes — from man to woman, from one to many — the adjective must change with it.
For an interpreter, this matters in two ways. First, in production: when you are interpreting a sentence that involves a description, you must produce the correct adjective form on the fly. The redeemed woman is la mujer redimida, not la mujer redimido. That final vowel change is small in pronunciation but large in correctness.
Second, in comprehension: when you hear a Spanish sentence, the adjective form tells you the gender and number of the subject even when the noun is not repeated. Están salvos means the people being referred to are masculine plural (or mixed group). Está redimida means the person being referred to is feminine singular. The adjective inflection carries information.
Ministry adjectives describe God, humanity, and the spiritual realities of the gospel. They are among the highest-frequency descriptive words an interpreter uses. They must be automatic in all four forms.
How Adjective Agreement Works
Standard Adjectives (Four Forms)
An adjective that ends in -o in its base form has four distinct forms:
| Singular | Plural | |
|---|---|---|
| Masculine | -o | -os |
| Feminine | -a | -as |
Example: nuevo (new)
| Singular | Plural | |
|---|---|---|
| Masculine | nuevo | nuevos |
| Feminine | nueva | nuevas |
el hombre nuevo / la mujer nueva / los hombres nuevos / las mujeres nuevas el nacimiento nuevo / la vida nueva / los pactos nuevos / las criaturas nuevas
This is the default pattern. Most Spanish adjectives follow it.
Invariable Adjectives (Two Forms — Singular/Plural Only)
Adjectives that do NOT end in -o in their base form typically have only two forms: singular and plural. The singular form is used for both masculine and feminine; only the plural changes.
| Singular | Plural | |
|---|---|---|
| Masculine and Feminine | fiel | fieles |
Example: fiel (faithful)
el hombre fiel / la mujer fiel / los hombres fieles / las mujeres fieles el siervo fiel / la sierva fiel / los siervos fieles / las siervas fieles
Other ministry adjectives in this category: grande/grandes, fuerte/fuertes, importante/importantes, humilde/humildes
Note: adjectives ending in a consonant also belong here: fiel/fieles, leal/leales, formal/formales
The Core Ministry Adjective Set
These are the adjectives most frequently used to describe people and realities in Christian ministry contexts. Master all four forms for each.
fiel — faithful
| Singular | Plural | |
|---|---|---|
| Both genders | fiel | fieles |
El siervo fiel. La sierva fiel. Los siervos fieles. Las siervas fieles. Dios es fiel. Sus misericordias son fieles.
Use: Describing faithful servants, a faithful God, faithful congregants.
salvo / salva — saved
| Singular | Plural | |
|---|---|---|
| Masculine | salvo | salvos |
| Feminine | salva | salvas |
El hombre salvo. La mujer salva. Los hombres salvos. Las mujeres salvas. Somos salvos por gracia.
Use: One of the most theologically important adjectives. Describes the saved state of believers. Appears in somos salvos, están salvos, ser salvo.
nuevo / nueva — new
| Singular | Plural | |
|---|---|---|
| Masculine | nuevo | nuevos |
| Feminine | nueva | nuevas |
El hombre nuevo. La criatura nueva. Los hombres nuevos. Las criaturas nuevas. El Nuevo Testamento. La nueva vida en Cristo.

| Singular | Plural | |
|---|---|---|
| Masculine | santo | santos |
| Feminine | santa | santas |
El Espíritu Santo. La Palabra Santa. Los santos de Dios. Las santas Escrituras.
Special note: Before masculine nouns beginning with a consonant, santo can shorten to san: San Pablo, San Juan, San Pedro (names of saints and places). Santo is retained before names beginning with vowels: Santo Tomás, Santo Domingo. Santa never shortens.
Use: Describing God’s holiness, the Holy Spirit, sacred texts, and members of the body of Christ as saints.
eterno / eterna — eternal
| Singular | Plural | |
|---|---|---|
| Masculine | eterno | eternos |
| Feminine | eterna | eternas |
El Dios eterno. La vida eterna. Los valores eternos. Las verdades eternas. Dios es eterno. Tenemos vida eterna.

|---|---|---|
| Masculine | perdido | perdidos |
| Feminine | perdida | perdidas |
El hombre perdido. La oveja perdida. Los perdidos. Las almas perdidas. Vine a buscar y salvar lo que se había perdido.
Use: Describing unsaved individuals, the lost sheep parables, and the spiritual state of those without Christ.
redimido / redimida — redeemed
| Singular | Plural | |
|---|---|---|
| Masculine | redimido | redimidos |
| Feminine | redimida | redimidas |
El pueblo redimido. La comunidad redimida. Los redimidos del Señor. Las almas redimidas. Somos redimidos por la sangre de Cristo.
Use: The redeemed people of God, the community of the redeemed, describing the state of those purchased by Christ’s blood.
The Oral Substitution Drill
This is the core drill for this lesson. It trains the reflex of adjusting adjective form as noun gender and number change. Do it aloud — writing it is not sufficient, because the goal is oral automatic production.
Base phrase: El hombre fiel
Step 1: Change the noun to feminine singular. La mujer fiel — adjective stays the same (fiel is invariable)
Step 2: Change to masculine plural. Los hombres fieles — adjective adds -es
Step 3: Change to feminine plural. Las mujeres fieles — adjective stays the same as masculine plural (invariable)
Now do the same with salvo:
El hombre salvo → La mujer salva → Los hombres salvos → Las mujeres salvas
Watch what happens: both the article AND the adjective change at every step.
Full substitution drill across all ministry adjectives:
| Base (Masculine Singular) | Fem. Sing. | Masc. Plural | Fem. Plural |
|---|---|---|---|
| El hombre fiel | La mujer fiel | Los hombres fieles | Las mujeres fieles |
| El hombre salvo | La mujer salva | Los hombres salvos | Las mujeres salvas |
| El hombre nuevo | La mujer nueva | Los hombres nuevos | Las mujeres nuevas |
| El hombre santo | La mujer santa | Los hombres santos | Las mujeres santas |
| El hombre perdido | La mujer perdida | Los hombres perdidos | Las mujeres perdidas |
| El hombre redimido | La mujer redimida | Los hombres redimidos | Las mujeres redimidas |
Read each row aloud, left to right, without pausing. When you can do the entire table in under 60 seconds without errors, the forms are becoming automatic.
Predicative Agreement
Adjectives do not only appear directly before or after nouns (attributive position). They also appear after ser or estar in predicative position — and they still must agree.
With ser: El pastor es fiel. — The pastor is faithful. La misionera es fiel. — The missionary (female) is faithful. Los pastores son fieles. — The pastors are faithful. Las misioneras son fieles. — The missionaries (female) are faithful.
El hermano es nuevo en la fe. — The brother is new in the faith. La hermana es nueva en la fe. — The sister is new in the faith.
With estar: Él está perdido. — He is lost. Ella está perdida. — She is lost. Ellos están perdidos. — They (m) are lost. Ellas están perdidas. — They (f) are lost.
The agreement rule is the same regardless of the verb. The adjective agrees with the subject noun, whether it appears right next to the noun or is linked by a verb.
Adjective Placement
After the Noun (Default Position)
In Spanish, most descriptive adjectives follow the noun. This is the opposite of English.
la gracia divina (divine grace) — not la divina gracia el Espíritu Santo (the Holy Spirit) los valores eternos (eternal values) la vida nueva (new life) — or la nueva vida (slightly different emphasis) los hermanos fieles (the faithful brothers)
Before the Noun (Emphatic or Inherent)
Some adjectives commonly appear before the noun for emphasis or when the quality is considered inherent rather than distinguishing:
el gran hombre (the great man — inherent quality) el pequeño niño (the little child) la gran comisión (the great commission) un buen pastor (a good pastor)
The position of bueno and malo changes meaning slightly: un hombre bueno — a good man (describing character) un buen hombre — a good man (more idiomatic, often complimentary)
For ministry interpretation, the standard position (after noun) is safe for all descriptive adjectives. Learning before-noun exceptions comes with exposure to native speech.
Practice Exercises
Exercise 1 — Four-Form Production
Write and say all four forms of each adjective:
- eterno: ___, ___, ___, ___

Exercise 2 — Agreement in Sentences
Complete each sentence with the correct form of the adjective in parentheses. Say the sentence aloud.
- La vida ___ (eterno) comienza ahora. → eterna
- Somos ___ (salvo) por la gracia de Dios. → salvos (assuming plural speaker)
- Las almas ___ (perdido) necesitan el evangelio. → perdidas
- El pueblo ___ (redimido) alaba a Dios. → redimido
- La Palabra de Dios es ___ (fiel). → fiel
- Somos criaturas ___ (nuevo) en Cristo. → nuevas (assuming female speaker or feminine noun)
- Los hermanos ___ (fiel) perseveran en la oración. → fieles
- El Espíritu ___ (santo) habita en nosotros. → Santo
- Las verdades ___ (eterno) no cambian. → eternas
- El siervo ___ (fiel) recibirá su recompensa. → fiel
Exercise 3 — Oral Substitution Speed Drill
Complete the full substitution drill table from this lesson (7 adjectives × 4 forms = 28 phrases). Aim for completion in under 90 seconds. Record yourself. Replay and check every adjective ending.
Exercise 4 — Ministry Sentence Pairs
For each pair of nouns, produce a complete sentence with the given adjective. Both sentences should be grammatically correct.
-
el misionero / la misionera + fiel: → El misionero es fiel. / La misionera es fiel.
-
el hermano / la hermana + nuevo in the faith: → El hermano es nuevo en la fe. / La hermana es nueva en la fe.
-
los creyentes / las creyentes + redimido: → Los creyentes están redimidos. / Las creyentes están redimidas.
-
la nación / los pueblos + perdido: → La nación está perdida. / Los pueblos están perdidos.
Common Errors in Ministry Adjective Agreement
Error 1: Forgetting the Feminine Form
*Los milagros es eterno — multiple errors. Correct: Los milagros son eternos.
*La vida es eterno — wrong adjective form. Correct: La vida es eterna.
Error 2: Over-Extending Invariable Rules
Students who learn that fiel is invariable sometimes apply that rule to salvo, nuevo, etc. *La mujer es nuevo — wrong. Correct: La mujer es nueva.
Error 3: Forgetting Plural Agreement
*Los hermanos son fiel — missing plural. Correct: Los hermanos son fieles.
*Las almas son perdido — both gender and plural wrong. Correct: Las almas están perdidas.
Key Takeaways for This Lesson
Before moving to Lesson 7:
- Standard adjectives ending in -o have four forms: -o, -a, -os, -as
- Adjectives not ending in -o have two forms: singular and plural (adding -s or -es)
- Adjectives agree with the noun they describe in both gender and number — in all positions (attributive and predicative)
- Know all four forms of the seven core ministry adjectives: fiel, salvo, nuevo, santo, eterno, perdido, redimido
- Santo before masculine names becomes san (San Pablo) but retains form in Espíritu Santo
- Adjectives typically follow the noun in Spanish; emphatic or inherent qualities may precede it
Daily Practice
5-minute adjective drill:
- Substitution drill — three ministry adjectives from the table, four forms each, aloud. (2 minutes)
- Three sentences using predicative adjectives after ser or estar. Change the subject’s gender and produce the correct form. (2 minutes)
- Identify two contexts today — a ministry news item, a Bible verse, a song lyric — where a Spanish adjective must agree with a noun. Note the form. (1 minute)
The goal by Lesson 7: when you describe any person or reality in your self-introduction, every adjective automatically matches the noun it modifies without any conscious checking.
