Feminine Plural
Since 'idea' is a feminine word, 'ideas' is also feminine and plural. Any words describing it (like adjectives) must also be plural and feminine: 'ideas originales'.
Gender Confusion
Mistake: “Using 'el ideas' or 'los ideas'.”
Correction: Always use the feminine article: 'las ideas' or 'unas ideas'. Even though the singular 'idea' ends in -a, it sometimes tricks learners because of other Spanish words ending in -a that are masculine (like 'el día').
