What is the greek word for all?

There isn't one single perfect Greek word for "all" as the best choice depends on the context. However, some common options include:

* πᾶς (pas): This is a very common word meaning "all," "every," or "the whole." It's often used with a noun in the masculine, feminine, or neuter form to agree with the noun's gender.

* πάς (pas): This is the same word as above, but in a different grammatical form (nominative masculine plural).

* πᾶσα (pasa): Nominative feminine singular of πᾶς.

* πάντα (panta): Nominative neuter plural of πᾶς, often used to refer to "everything" or "all things."

* ὅλος (holos): This means "whole," "entire," and can imply "all" in the sense of completeness.

The best translation will depend on the specific nuance you want to convey. For example, "all the people" might use πᾶς ὁ λαός (pas ho laos), while "everything" might be πάντα (panta).
