insteadyoudaoicibaDictYouDict[instead 词源字典]
instead: [13] Instead is the English end of a chain of loan translations that goes back to Latin in locō (in loan translations, the individual components of a foreign word or expression are translated into their equivalents in the borrowing language, and then reassembled). The Latin phrase meant literally ‘in place (of)’, and this was translated into Old French as en lieu de.

Middle English rendered the French expression in turn as in stead of or in the stead of (stead ‘place’, now obsolete except in certain fixed compounds and expressions, comes ultimately from the same Indo-European source as stand, station, etc). It began to be written as one word towards the end of the 16th century.

steadyoudaoicibaDictYouDict
stead: [OE] Stead ‘place’ comes from a prehistoric Germanic *stadiz, which also produced German statt ‘place’ and stadt ‘town’. This in turn went back to Indo-European *stətís, a derivative of the base *stə -, *stā- ‘stand’, which also produced English stand and Latin stāre ‘stand’ (source of English state, statue, etc). The expression in the stead of ‘in place of’, and its lexicalized form instead, originated in the 13th century, modelled on Old French en lieu de.
