水みずが合あわない

expression, i-adjective

not suit one; not agree with one; feel out of place

Idiomatic expression used when a new environment, lifestyle, job, or social circle does not suit someone, causing discomfort or difficulty fitting in. The literal meaning 'the water does not agree with one' is the origin, but it is now used broadly for any situation where one feels out of place.

  I changed jobs, but this company just doesn't seem to suit me.

• 引ひっ越こしてから体たい調ちょうを崩くずしがちで、この土と地ちは水みずが合あわないのかもしれない。

  Since moving, I've been getting sick easily; maybe this place doesn't agree with me.
