What is the difference between using the verb use in the form "Χρησιμοποιήστε" and "Χρησιμοποίησε"? is one of them used to give order to plural while the other to one person??
According to the Duo notes, verbs that end in -ώ are supposed to be conjugated with an -α ending for the singular. Why is this not χρησιμοποίησα?
