Causing discomfort; unpleasant or disagreeable.
From discomfort + -able (able to be, capable of), forming an adjective; discomfort itself comes from dis- + comfort, from Old French conforter (to strengthen).
This word is somewhat archaic — modern English prefers 'uncomfortable' — but 'discomfortable' actually makes logical sense because the -able suffix means 'able to cause,' so 'discomfortable' means 'able to cause discomfort' while 'uncomfortable' means 'full of discomfort.'
