(comparative more ident, superlative most ident)
From a later form of ithand, itself an alteration (due to assimilation to 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 + -and and/or ithe + -en. Cognate with Icelandic iðinn (“diligent”), Norwegian idig (“busy”), Danish id (“pursuit, calling, business”). More at ithand.
