This is the 750th most frequent Azerbaijani word.
tez
"Tez" means "fast" or "quick" in English.
Here, 'tez' is used to mean 'quickly', denoting the manner in which the action (finished work) was performed.
O, işini tez bitirdi.
He finished his work quickly.
In this sentence, 'tez' is used in a contextual expression urging to speed up or act quickly.
Tez ol, gecikirik.
Hurry up, we are getting late.
Here again, 'tez' is used to describe the swiftness or shortness of the time taken to perform the action.
