Explanation:

1. In Spanish grammar, most feminine adjectives end with "a", and most masculine adjectives end with "o".
2. Adjectives that can be either masculine or feminine (epicene adjectives) often end with "e" (like "inteligente") or "ista" (though "e" is more common for this type, e.g., "simpático" has a feminine "simpática", but "inteligente" is same for both; another common ending for invariable in gender is "e" or sometimes "ista" but "e" is a key one here).
3. The two singular definite articles in Spanish are "el" (masculine singular) and "la" (feminine singular). The two singular indefinite articles are "un" (masculine singular indefinite) and "una" (feminine singular indefinite).
4. In Spanish, adjectives come after the nouns they describe (e.g., "la casa bonita" - "the pretty house", where "bonita" (adjective) is after "casa" (noun)).
