Learn French: Ça y est, je finis mon travail. - That's it, I am finishing my work.

Word-for-word, ça y est translates to "that there is," but it is a very common set phrase. French speakers use it to mean "That's it!", "It's done!", or "Finally!". You can use it right when you finish a task, just like in this sentence.

Does je finis mean "I finish" or "I am finishing"?

It means both! French does not have a separate "am doing" tense like English. You just use the standard present tense je finis for both "I finish" and "I am finishing".

finir (to finish) is a regular verb ending in -ir. When talking about yourself using je (I), the present tense ending is -is. If you were talking about someone else, like il (he) or elle (she), it would end with a "t": il finit.
