What does it mean in spanish?

If the question is asking how to say "it" in Spanish, this is a little complicated. In English, it can serve in many different positions.

If "It" is the subject, then it is simply omitted in Spanish. There is no equivalent. For example, "It is big." would be "Es grande", which literally means "Is big". The "It" is implied.

If "It" is the direct object, then it is "lo" or "la" depending on the gender of the noun referred to. For example, "I want it [a pencil]" would be "Lo quiero [un lápiz]."

If "It is the indirect object, then it is "le". For example, "I feed food to it" would be "Le doy de comida."

Of course, there are many expressions in English that use "it" in a different context than these main uses such as "That's it!" or "You'll know it when you see it!" or "It comes and goes!" or "It's enough!", etc. which have unique translations into Spanish.
