### Etymology

### Pronunciation

* IPA: /ai̯/
* Rhymes: -ai̯

### Particle

ai
* interrogative particle (used when a non-verbal element is fronted for emphasis)

* whether, if (used when the subordinate clause has a non-verbal element fronted for emphasis)

#### Usage notes

* Used before a non-verbal element fronted for emphasis. Unemphatic initial verbs, on the other hand, employ the interrogative particle a.
* This word is found in formal language. As an initial interrogative particle, it is often dropped altogether in colloquial language or replaced with ife in some southern dialects.
* Likewise, with the meaning "whether", this may be dropped colloquially. An alternative construction influenced by English is to replaced the ai with os (“if”) followed by the appropriate dialect-specific indicating an emphatic subordinate clause, namely taw in south Wales and mai or na in the north.
