fain

the word 'fain' originates from the old english 'fægen', meaning 'glad, joyful, or well-pleased'. it is related to the old norse 'feigr' and the old high german 'fagan', all sharing a common germanic root conveying a sense of gladness or eagerness. over time, its usage shifted from describing a general state of joy to specifically denoting a willing or eager disposition, often with a slightly archaic or poetic tone. it survives in modern english primarily in literary contexts, carrying the core sense of doing something with pleasure or readiness.

this word is a simplex form derived from old english.
