Tight

Fitting closely and firmly, with little or no space to move. It can also mean difficult, limited, or strict, like a tight schedule or tight security.

From Old English 'tēon' (to draw, pull) and related Germanic roots, but 'tight' as we know it appears clearly in Middle English, influenced by Scandinavian words like Old Norse 'þéttr' (tight, close). The core idea is drawn or stretched firmly. Its meanings expanded into emotional and financial contexts.
