🎤Pronunciation
🌳Etymology
Origin
Unshakable is a modern English formation combining the Germanic verb 'shake' (from Old English 'sceacan', meaning to move back and forth) with the Latin-derived suffix '-able' (from Latin 'habilis', meaning capable or able) and the Germanic negation prefix 'un-'. The word emerged in Middle English as a straightforward compositional term expressing the inability to be shaken, whether physically or metaphorically.
Breakdown
un- (not, negation) + shake (to move back and forth; from Old English sceacan) + -able (capable of; from Latin habilis). The formation reflects the common English pattern of negating adjectives through the un- prefix applied to shake + -able.
