Questions & Answers about Το μαλλί μου είναι ακόμα βρεγμένο από το ντους.
Yes. μαλλί can mean both hair and wool in Greek.
Context tells you which one is meant:
- το μαλλί μου
- βρεγμένο από το ντους clearly means my hair
- in other contexts, μαλλί can mean wool as a material
So this is one of those words whose meaning depends strongly on the situation.
Greek can talk about hair in two ways:
- το μαλλί μου = my hair, seen as one mass / overall hair
- τα μαλλιά μου = my hair, seen as plural hairs
Both are possible. For a person's hair, many learners will hear τα μαλλιά μου very often, and Τα μαλλιά μου είναι ακόμα βρεγμένα is a very natural alternative.
So the sentence is not wrong; it is just using the singular collective idea of hair.
Because Greek normally keeps the definite article with possessed nouns.
So Greek says:
- το μαλλί μου = literally the hair my
- το σπίτι μου = my house
- η αδερφή μου = my sister
This is completely normal Greek structure. The article does not disappear just because you have μου.
