Questions & Answers about Soy inteligente e impulsivo.
Why does this sentence use e for "and" instead of y?
Is the person speaking male or female?
The speaker is male. We know this because the adjective impulsivo ends in -o, which is the masculine form. If a woman were speaking, she would say Soy inteligente e impulsiva.
If the speaker is male, why doesn't inteligente end in -o?
Spanish adjectives that end in -e (like inteligente, interesante, or grande) are gender-neutral. They stay the same whether they are describing a male or a female. You only change them when making them plural (by adding -s).
