Etymology
From a later form of ithand, which was itself an alteration (through assimilation to the suffix -and) of Middle English ithen, from Old Norse iðinn ("assiduous, diligent"), from iðja, iðna ("to do, perform"), from ið ("a restless motion"); equivalent to ithe plus -and and/or ithe plus -en. Cognate with Icelandic iðinn ("diligent"), Norwegian idig ("busy") and Danish id ("pursuit, calling, business"). See further at ithand.
