In a state of being askew, crooked, or not straight; awry.
From prefix 'a-' + Scottish/Northern English 'glee' (meaning awry or crooked). The word is primarily Scottish in origin and has been used since at least the 1700s.
Robert Burns used this word in his poetry, and it's the direct ancestor of the phrase 'agley' made famous in 'To a Mouse'—when he wrote 'the best laid plans o' mice an' men gang aft agley,' he was using this Scottish gem.
