What does the greek word dict mean?

There's no Greek word "dict". There are a couple of possibilities:

* You might be thinking of the Greek word "δικαιοσύνη" (dikaiosyne), which means "justice" or "righteousness". This word is the root of the English word "dictum", meaning "a formal pronouncement" or "a statement of principle", which is also related to the word "dictate".

* You might be thinking of the Latin word "dictum". This word, which means "a formal pronouncement", is often used in English. It is also the root of words like "dictate" and "dictator".

It's important to remember that English words are often borrowed from other languages. While "dict" isn't a Greek word itself, it has roots in Greek words that have influenced its meaning.
