Problem with some 縮約形

Question

I just came across some of the "contracted forms" used in conversations, which I'm not really familiar with. May you help me decoding the ones that I found impossible to understand and to translate them into the more "common" form?

I will explain it better, for example in this sentence: "あしたいちんち、どっか出掛けよっか。", I do understand that どっか is どこか and that 出掛けよっか is 出掛けようか, but I cannot figure out what いちんち means.

I also found: "何すんの", which I believe corresponds to "何するの", but I'm not really sure about it.

The last one that I cannot understand is 買ってこよっか, as in: "何か飲むもんでも、買ってこよっか".

Thank you in advance.

Answer 1

あしたいちんち　 >>> 　明日一日 【あしたいちにち】

どっか 　　　　　>>> 　どこか

出掛けよっか　　 >>> 　出掛けようか 【でかけようか】

何すんの　　　　 >>> 　何するの 【なにするの】

飲むもんでも　　 >>> 　飲【の】む物【もの】でも　

買ってこよっか　 >>> 　買【か】ってこようか

The first one いちんち is somewhat rare but there are other words like it which can have similar contractions when certain vowel+consonant combinations occur.

For example おれのうち becoming おれんち.

Answer 2

すんの and ～よっか are extremely common casual contractions of するの and ～ようか.

いちんち, on the other hand, I've never seen before, and to me it looks more like a typo than anything at first glance. Where did you see this? From the context, I would guess it's a contraction of 一日 (いちにち), but I don't think it's a particularly common one.

A little searching suggests that this may actually be a dialectal word, clearly deriving from 一日 but with slightly different usages depending on the source region.
