the word "uneasily" is built upon the core concept of "ease," which entered english from old french 'aise,' meaning "comfort or opportunity." the prefix 'un-', of germanic origin, is a prolific negator, turning the state of ease into its opposite. the adverbial suffix '-ly,' also from old english, transforms the adjective "uneasy" into a modifier describing the manner of an action. thus, the literal construction "not comfortably" evolved to describe actions performed with anxiety, restlessness, or physical discomfort.

Structure: un (not) + easi (comfortable) + ly (adverb suffix) un- (old english, a prefix meaning "not"); easi (a variant of the root from middle english 'ese', old french 'aise', meaning "comfort, ease"); -ly (old english, an adverbial suffix)
