ya

Ya is one of the most versatile and nuanced adverbs in Spanish, carrying different meanings depending on tense and context. In the present perfect it means "already"; in the present tense it signals immediacy or impatience ("ya voy" - I am coming); combined with a negative it means "anymore" ("ya no" - no longer). In informal speech it can even function as a back-channel acknowledgement, similar to "yeah, right" or "I get it."

The negative construction ya no (no longer) is often confused with todavía no (not yet). "Ya no como carne" means you used to eat meat but have stopped; "Todavía no como carne" means you have not eaten it yet but might. Getting this right signals genuine fluency.
