Mnemonic

Iyaa (いやあ) is a Japanese interjection — surprise, embarrassment, awe, hedging. It looks like iya (refusal — already covered) + long aa, but semantically it is a separate interjection. Functions like English "oh / well / wow." Uses: (1) surprise — "iyaa, sugoi" (wow, amazing), (2) embarrassment / hedging — "iyaa, sore wa..." (well, that's..., buying time), (3) modest disclaimer to praise — "iyaa, sonna koto nai desu yo" (oh, that's not really so). Interjection cluster: uwaa (big surprise), e! (immediate shock), maa (well / kind of, soft acknowledgment), haa (sigh / understanding / resignation). A conversational lubricant — awkward to non-native learners but central to natural Japanese flow. Iya (short) "no" vs iyaa (long) "oh" — distinguished by length. Korean "aigo / eoikku / wa / geulsse / mwo" parallels.
