What does at mo mean in Greek?

"At mo" doesn't have a direct translation in Greek as a single phrase. It's likely a transliteration or a very informal, possibly dialectal, spelling attempting to represent a Greek expression. Without more context (like the sentence it's used in), it's impossible to say for certain what it means.

To help me figure it out, could you provide more context? For example:

* Where did you see this phrase? (e.g., a book, a website, someone speaking)

* What was the surrounding conversation or text?

* What is the intended meaning, if you know?

Knowing this will allow me to provide a more accurate interpretation.
