also: やや
Kansai dialect interjection expressing refusal, rejection, or strong dislike. Equivalent to standard Japanese 嫌だ or やだ. Often used in casual, emotional contexts.
「一緒に行かへん？」「いやや、行きたない。」
"Won't you come with me?" "No, I don't want to go."
そんなんいやや！
I don't want that! / No way!
Kanji spelling is possible but uncommon; kana is preferred.
Alternate reading; less common than いやや.
Kansai dialect contraction of 嫌 (iya, 'disagreeable') + や (ya, dialectal copula). The alternate reading やや is a further reduction.
