phrase "left of leaves"

[Zaccarihas]

How can I tell by the phrase that they already "left" for the coast - couldn't it be "leaves" for the coast?

You probably need to restate your question, providing more information or details regarding the message you wish to convey.

Still, I will take a wild guess and answer "they have/had left for the coast"

[Vanity Fair]

I agree with Thanos, but one more thing you have to pay attention to:if you use the pronoun THEY, you can't say "leaves" for present simple tense but "leave" since the form "leaves" is for the third person singular!

And "already" in the sentence points out that the action already started or is completed so you have to use have/had left.

They have left for the coast. (present perfect -- the activity is in the past)

They left for the coast. (simple past tense -- the activity is in the past)

They will have left for the coast by the time you arrive. (This refers to a future activity which will be finished before another future activity takes place.)
