The compound 'too-tight' is a transparent modern English formation, combining the intensifying adverb 'too' with the adjective 'tight'. 'Too' originates from Old English 'tō', which served as a preposition and adverb for direction and addition, eventually specializing in expressing excess. 'Tight' has a more complex journey, evolving from Middle English and Old English terms related to density and strength, influenced by Old Norse 'þéttr' (watertight, close in texture). The logic of the compound is straightforward and literal: it directly describes the condition of being excessively constrictive or closely fitted, moving from two independent concepts of degree and state to a single descriptive term for discomfort or improper fit.

Structure: too (excessively) + tight (firmly fixed/constricted) - too: From Old English 'tō', an adverb meaning 'in addition, also, excessively'. It functions as an intensifier in this compound. - tight: From Middle English 'tiht, tyght', meaning 'dense, solid, impermeable'. It is an adjective describing a state of constriction or close fit.
