bind: [OE] Band, bend, bind, bond, and bundle can all be traced back ultimately to an Indo- European base *bhendh-, which was also the source of Sanskrit bandh ‘bind’ and Greek peisma ‘cable’. In the case of bind, the immediate precursor of Old English bindan was the Germanic stem with an i vowel, *bind-. In the 14th century the verb came to be used as a noun, for the ‘stem of a climbing plant’, from which we get bine (as in woodbine ‘honeysuckle’). => band, bend, bond, bundle
Old English bindan "to tie up with bonds" (literally and figuratively), also "to make captive; to cover with dressings and bandages" (class III strong verb; past tense band, past participle bunden), from Proto-Germanic *bindan (cognates: Old Saxon bindan, Old Norse and Old Frisian binda, Old High German binten "to bind," German binden, Gothic bindan), from PIE root *bhendh- "to bind" (see bend (v.)). Intransitive sense of "stick together" is from 1670s. Of books, from c. 1400.
