Questions & Answers about Σήμερα όλα είναι καλά.
- Σήμερα = today → adverb of time (says when).
- όλα = everything / all (things) → neuter plural pronoun (subject).
- είναι = is / are → 3rd person form of the verb είμαι (to be).
- καλά = well / fine / good → here it functions like an adverb or a neuter plural adjective meaning in a good state.
So the structure is basically: Today – everything – is – fine.
Greek usually does not use subject pronouns when the subject is understood from context or from the verb form.
In this sentence, the subject is όλα (everything), so there is no need for an extra it. English might say “Today *it is all fine”* in some versions, but Greek just uses:
- όλα είναι καλά = everything is fine
(no extra pronoun needed).
