pissed

the adjective 'pissed' originates from the verb 'piss', which has roots in old french 'pissier', likely of onomatopoeic origin, imitating the sound of urination. by the late 19th century, 'pissed' emerged as a past participle used adjectivally, initially carrying the literal sense of having urinated. the figurative slang meanings developed in the 20th century: in british english, "pissed off" (angry) was shortened to 'pissed', drawing a metaphorical link to venting or releasing frustration. concurrently, in american english, the term evolved to mean 'drunk', likely from the concept of being so intoxicated as to lose bladder control, completing its journey from a literal bodily function to abstract states of extreme emotion or intoxication.

the word is a simplex form derived from the verb 'piss'. it is not productively segmented into smaller, meaningful morphemes in modern english.
