"He is like his father."

Translation: Tá sé cosúil lena athair.

Is "Tá sé cosúil lena hathair" = "He is like her father."?

[galaxyrocker]

Yep.

Would you use this sentence to say that he looks like his father or does it also refer to his behaviour being like his father. And I have to ask another question concerning the English sentence. Would you say he is like his father for both meanings, look like and behave like?

[SatharnPHL]

Yes, in both languages, in the appropriate contexts.

"You'd recognize him all right - he's just like his father".
"D'aithneofá é ceart go leor - tá sé díreach cosúil lena athair"

"He's always in bed by 11, just like his father"
"Tá sé ina leaba faoi 11 a chlog i gcónaí, díreach cosúil lena athair".

Thank you so much for all your help and further explanations. The only way to show my appreciation is to give you a lingot...

Does this literally mean "There is similarity with his father" ??

[SatharnPHL]

No. There is no "sé" in your suggestion.
