@Saad579687 Yes and no. In British English, biscuits refer to the (usually small) hard baked products, which can be either savory or sweet, while cookies refers to the larger, soft/moist kind. In American English, we use cookie for both the hard and the soft kind, but only for sweet ones.
Biscuits in the US aren't sweet either, they're like a scone sized drop bread (I've only had buttermilk biscuits, and they're dense but somehow slightly airy & flaky.) Biscuits in UK can be a lot of things we'd call cookies and crackers here in the US. American biscuits are really good though! (If you've had an idli from southern India, it has that same dense but fluffy quality - although the ingredients are different.
If we were writing with niqqud it would have been עוגיה. The rules for writing without niqque are that the suffix /iya/ is written with two yods. the plural /yot/ with one yod. There is reason behind it - arguably it minimizes ambiguity (not that there isn't still ton of it).
