Morphology
The compound combines a sense of 'wing' (a side or faction) with the colloquial 'nut' (an eccentric or crazy person), so if a learner can access the political sense of 'wing' and the slang sense of 'nut' they can infer it denotes an extreme or irrational person on a political side. However, both senses are metaphorical/colloquial rather than literal (and 'wing' as a political faction may not be known from the basic definition), so the meaning is only partially predictable to a B1 learner.
Etymology
Wing nut is a tree named for the small nut fruits that have thin, flat wings which help them drift away from the tree like tiny wings. So the name comes from how the tree's fruit looks and moves.
