Do you add an if a word is feminine?

It seems like you're asking about the grammatical concept of adding an article (like "a" or "an") before a noun. This is related to gender in some languages, but not in English.

In English, we don't add an "a" or "an" based on whether a noun is feminine or masculine. We use "a" before words that start with a consonant sound and "an" before words that start with a vowel sound.

For example:

* A cat (cat starts with a consonant sound)

* An apple (apple starts with a vowel sound)
