talk, (kokuji)
噺 centers on spoken narrative: talking, telling a story, or a tale. It is a Japanese-coined character (kokuji) specifically for 'story' or 'talk'.
噺 is a kokuji (Japanese-coined character) combining 口 (mouth) with 新 (new), likely to express 'new talk' or 'story'. The exact historical development is uncertain, but it is a relatively modern creation.
A mouth 口 speaking something new 新: a fresh story or talk.
For はなし, picture a mouth 口 telling a new 新 story that makes everyone laugh: 'Ha! Nashi!' (はなし) — the story is so funny it sounds like 'ha-nashi'.
