Questions & Answers about Ο φίλος μου είναι πολύ αστείος.
Word by word:
- Ο – the (masculine singular definite article, subject)
- φίλος – friend (male friend, or grammatically masculine “friend”)
- μου – my (literally “of me”; unstressed possessive pronoun)
- είναι – is (3rd person singular of “to be” – είμαι)
- πολύ – very
- αστείος – funny (masculine adjective)
So literally: The friend of-me is very funny.
In Greek, a noun used as a specific person/thing is usually preceded by the definite article. Possessives like μου, σου, etc., do not replace the article.
So:
- Ο φίλος μου = my (specific) friend
- Η μητέρα μου = my mother
- Το σπίτι μου = my house
Leaving out the article (Φίλος μου είναι πολύ αστείος) is possible in some contexts, but it sounds more stylistic/poetic or very colloquial. The safe, standard form is Ο φίλος μου.
