When you start learning Greek, one of the verbs you will use often is “μιλάω” (“milao”), which means “to speak or to talk”.
For example, the following sentences might be very useful to know, when you travel in Greece:
“δεν μιλάω καλά ελληνικά” = “I do not speak Greek well”.
“μιλάτε αγγλικά;” = Do you speak English?
