Etymology
The word 'unguided' is a Modern English formation built upon the older verb 'guide'. The core morpheme 'guid' traces back to the Old French 'guider', meaning to lead or direct, which itself has Germanic roots, possibly related to the Proto-Germanic wītaną, meaning "to know" or "to go." The Old English prefix 'un-' is a prolific negator, directly applied to the past participle form 'guided' created with the adjectival suffix '-ed'. The literal construction "not led" logically evolved into its contemporary meanings, describing anything from a lack of personal direction to the specific technical sense of a missile flying without external control.
