Distinguishing 'ai' as interrogative vs. indefinite
'Ai' as an interrogative pronoun is typically used in questions and is often accompanied by a question mark. As an indefinite pronoun, it appears in statements and can be paired with other words like 'đó' (someone) or 'cũng' (anyone/everyone).
词源
From Proto-Vietic *ʔaːj, related to Proto-Mon-Khmer *ʔaːj. Cognate with Muong ai and possibly Thai ไอ (ai).
用法说明
In Vietnamese, 'ai' is always used with the question mark (?) in writing for interrogative sentences. It can also function as a relative pronoun in some contexts, though this is less common.
