"Το αγόρι είναι μικρό."

Translation: The boy is small.

[MarksAaron]

"Micro". Nice

[dooooooduo]

Just realised that μικρό=micro..

[Moha_Gaber]

shouldn't be :
το αγόρι έστί μικρο
είναι --> to be
εστί --> ( he , she , it ) is

[troll1995]

Yes, in Ancient Greek. Modern Greek lacks infinitives and είναι has replaced both εστί and εισίν.

[AchintyaJa6]

What is the meaning of mikro?

[mizinamo]

small

[Sue919013]

I find it really difficult to distinguish the difference in sound between "ν"and "μ" in είναι και είμαι. I do try but it's very hard.

That's understandable in a new language. You can try this link with native Greek speakers. Listen to as often as you like to get used to the sounds

The boy is young.
It is right and acceptable!
