crabbed

the word crabbed derives from the middle english 'crabbed', an adjective formed from the noun 'crab'. the association stems from the crab's perceived characteristics: its sideways, awkward movement and its propensity to pinch, which metaphorically suggested a perverse, irritable, or difficult temperament. by the 14th century, this extended to describe handwriting that is cramped, irregular, and difficult to decipher, mirroring the awkward, tangled appearance of a crab's legs. thus, the literal animal lent its name to two abstract qualities—ill temper and illegible writing—through shared connotations of awkwardness and unpleasant difficulty.

Structure: crab (crab) + ed (adjective suffix) crab (from old english crabba, meaning the crustacean, used here for its associated irritable or sideways-moving character) + ed (from old english -ede, a suffix forming adjectives, often from nouns, indicating possession of a quality)
