Difference between Blunder and Botch

BLUNDER vs BOTCH: NOUN

Synonyms Error, Mistake, Blunder, Bull. An error is a wandering from truth, primarily in impression, judgment, or calculation, and, by extension of the idea, in conduct; it may be a state. A mistake is a false judgment or choice; it does not, as error sometimes does, imply moral obliquity, the defect being placed wholly in the wisdom of the actor, and in its treatment of this defect the word is altogether gentle. Blunder is a strong word for a mistake which is stupid, a gross error in action or speech. A bull is a blunder in language, involving generally a very obvious and comical contradiction; but the word is sometimes applied to any particularly inapt or ludicrously inappropriate remark.
