tillyoudaoicibaDictYouDict[till 词源字典]
till: English has three distinct words till, but two of them are probably related. The etymological notion underlying till ‘cultivate the soil’ [OE] is of ‘striving to obtain a goal’. Indeed, that is what its Old English ancestor tilian originally meant; ‘cultivate’ is a late Old English development, via an intermediate ‘labour’. The verb comes from a prehistoric Germanic *tilōjan, a derivative of the noun *tilam ‘aim, purpose’ (source of German ziel ‘goal’).

This passed into Old English as till ‘fixed point’, which seems to have been converted into a preposition meaning ‘up to a particular point (originally in space, but soon also in time)’. The compound until dates from the 13th century; its first element was borrowed from Old Norse *und ‘till’. The origins of till ‘money box’ [15] are uncertain.

Each [i.e. socialism, communism, anarchism] stands for a state of things, or a striving after it, that differs much from that which we know; & for many of us, especially those who are comfortably at home in the world as it is, they have consequently come to be the positive, comparative, & superlative, distinguished not in kind but in degree only, of the terms of abuse applicable to those who would disturb our peace.

The sense connection in the various Germanic forms is perhaps "strive, make a strong effort;" the senses having to do with walking and standing are found only in English and Low German.
