"Oni się lubią."

Translation: They like each other.

[jawa500]

I find this and the previous example confusing regarding the need for "nawzajem";

oni się rozumieją nawzajem

oni się lubią

[Vengir]

„Nawzajem” means "each other", but if the context is known, it can be dropped. Without „nawzajem” this sentence can be understood in two ways: "they like each other" (A likes B and B likes A) or "they like themselves" (A likes A and B likes B).

My first idea was They like themselves.

[Jellei]

Which actually works as it is a correct interpretation.

“They like themselves” was not accepted in my case, but there seems to be a clear difference in meaning between that rendition and “they like each other”.
