the word 'tights' originates from the adjective 'tight', which entered english from old norse þéttr, meaning dense or close in texture. this term is related to middle high german dīhte and has a proto-germanic root. the garment is named for its close-fitting, constricting nature, directly linking the physical property of being 'tight' to the clothing's defining characteristic. the plural form 'tights' emerged in the late 18th century to describe skin-tight breeches, evolving in the 20th century to refer specifically to sheer, close-fitting legwear. this evolution demonstrates a straightforward metonymic process where a descriptive adjective becomes the name for an object defined by that very quality.

the word is a simplex form derived from the adjective 'tight'. it is of middle english origin, from old english thīht, thyht (dense, solid, firm), of germanic origin.
