'gangly' originates from the English dialect word 'gangling,' which is derived from the verb 'gang,' meaning 'to go or walk.'

'gangling' transformed into the modern English word 'gangly' to describe someone who moves awkwardly due to their height and thinness.

Initially, it meant 'to walk awkwardly,' but over time it evolved into its current meaning of 'tall, thin, and awkward.'
