† bitwihprep.

Etymology: Old English Anglian bi-, betwíh, Saxon betwĭh, -tweoh, -twuh, -tuh , -twioh , -twyh , < bi- , be- prefix + twíh , etc., probably shortened from the old accusative form *twîhn (twihn , tweohn ; twîhen , twîhon ) mentioned as one of the sources of between prep., adv., and n. The original construction of twíh is seen in the phrase mid unc twíh ‘amid us twain,’ i.e. ‘between us’; from a parallel bi (unc ) twíh , bi twíh , came the combined betwih . In bitwuht , the -t must have been added on the analogy of betwixt. Only in Old English; superseded in Middle English by the expanded form bitwihen prep.
