Explanation:

When we are producing sentences in Spanish we need to focus our attention in CONCORDANCE between the sentence’s parts; at this respect, we have to remember that the CONJUGATED VERB has to match with the MAIN NOUN, which will be the subject of our syntactic construction. But that’s not all, inside all the NOMINAL PHRASES the elements also have to match with each other.

NOMINAL PHRASE: It is composed of a NOUN and its modifiers that could be articles, adjectives, adverbs and other nouns.

In our exercise, we have to complete our sentences with adjectives that would be qualifying the noun; NOTICE HOW WE CAN MAKE SENTENCES OR NOMINAL PHRASES:

1. La profesora de historia es guapa (SENTENCE)

La guapa profesora de historia (NOMINAL PHRASE)

2. David y Simón son guapos (SENTENCE)

Los guapos de David y Simón (NOMINAL PHRASE)

3. El artista es simpático (SENTENCE)

El simpático artista (NOMINAL PHRASE)

4. Esas musas son delgadas (SENTENCE)

Esas delgadas musas (NOMINAL PHRASE)

5. El abuelo de Alberto es viejo (SENTENCE)

El viejo abuelo de Alberto (NOMINAL PHRASE)

6. La programadora es trabajadora (SENTENCE)
