A state of confusion or bewilderment.
From 'bemuddle' plus the suffix '-ment' (from Old French, meaning a condition or result). This creates a noun describing the state of being bemuddle.
The fact that we have 'bewilderment' and 'confusion' as modern nouns, but rarely 'bemuddlement', shows how English standardized by selecting one winner among competing synonyms—linguistic survival of the fittest!
