1. (semiotics) Oppositions (typically binary oppositions) are culturally widespread pairings of concepts (such as male/female and mind/body) that are seen by structuralist theorists as part of the deep structure underlying the surface features of major texts and cultural practices. Oppositions are fundamental in the structural analysis of such forms.
2. (semantics) Opposing terms graded on the same dimension that do not exhaust its possibilities (e.g. good–bad, where ‘not good’ is not necessarily ‘bad’); differences of degree (in some contexts termed logical contraries).
