'tongue-tied' originates from Middle English, specifically the word 'tunge-tied,' where 'tunge' meant 'tongue' and 'tied' meant 'bound or fastened.'

'tunge-tied' transformed into the modern English word 'tongue-tied' through Middle English.

Initially, it meant 'having the tongue physically tied or restricted,' but over time it evolved into its current meaning of 'unable to speak due to nervousness or embarrassment.'
