Etymology
the word 'hitherto' is a compound formed from two old english elements, 'hither' and 'to'. 'hither' originally meant 'to this place', while 'to' functioned as a directional preposition. the literal sense of the compound was thus 'to this (point)'. over time, this spatial meaning evolved into a temporal one, shifting from indicating a physical destination to marking a limit in time. this semantic shift from space to time is a common pattern in language evolution. consequently, 'hitherto' came to mean 'up to this time' or 'until now', preserving the sense of a boundary or limit established by its original components.
Analysis
Structure: hither (to this place) + to (toward)
