What is the difference between "Ακούστε!" and "Άκου"? is one used to give order to a group while the other to one person?
Ακού! - Singular, imperfective
Ακούτε! - Plural, imperfective
Ακούς! - Singular, aorist
Ακούστε! - Plural, aorist
The imperfective is used for the shorter period of time? Or is it the opposite?
The imperfective is used for ongoing actions: https://en.wikipedia.org/wiki/Imperfective_aspect, https://en.wikipedia.org/wiki/Perfective_aspect.
Okay i understand it now. Thanks!
Why is "hear!" wrong? ακούω is "I hear"!
I think it's because no one uses hear as an imparative in English
Hear ye! Hear ye!
Hear the birds sing!
Is it just me or does the speaker's intonation make all exclamations sound like questions?
You're right, this one at least does sound like a question...
I would dare to say that "Hear! Hear!" is used as an imperative in the House of Commons.
Does it help?
How would you say "do you hear?", as in: "do you hear a sound?"
