the modern english word "till" has a dual heritage. its primary use as a preposition and conjunction meaning "until" stems directly from old english til, meaning "to" or "until," a word of ancient germanic lineage. this prepositional sense is shared with its old norse cognate til, suggesting a common proto-germanic ancestor. in a separate development, the verb "to till" (the soil) originates from the old english verb tilian, meaning "to strive for, obtain, or cultivate," which is etymologically related to the noun til, meaning "good" or "suitable." the conceptual link lies in the labor directed towards making land good and suitable for crops. over centuries, the preposition/conjunction and the verb, while phonetically identical, have followed distinct but parallel semantic paths into modern english.

the word "till" is a simplex form. its core is derived from old english til, of germanic origin, related to old norse til. its function as a preposition and conjunction is native to the germanic languages.
