"Tình yêu không cần định nghĩa."

Translation: Love does not need definition.

[Lechuza-chouette]

Love does not need a definition.

[Dan553966]

In terms of Vietnamese grammar, is "định nghĩa" a noun or a verb here?

[vngdhuyen]

I think it could actually be both. just like viết can take passive voice (quyển sách này viết về lịch sử: this book is (written) about history), định nghĩa can also take passive voice without passive marker được or bị.

• love does not need a definition.
• love does not need to be defined.
