"It is a plate."
Translation:Is pláta é.
bí can't be used for identification or classification clauses. Indtead, the copula is must be used. So, if it has two nouns, use is
Ok thanks! So for saying what something is you use is é and for like how sonething is you can say tá sé?
You've got the idea! Tá an pláta gorm. The plate is blue. Is pláta é. It is a plate
How can you tell its é not í? Are there genders in irish like in french?
That's exactly right. Irish, like French, has masculine and feminine nouns, but no nouns that are neuter ("it").
There are some endings that indicate whether the noun is masculine of feminine, but it really helps to learn, not just pláta but an pláta because the article an causes the first consonant of a feminine nouns to lenite, if possible. Páirc, which is feminine, becomes an pháirc, but gort, which is masculine, stays an gort.
