'tongue-related' originates from the English word 'tongue' combined with the suffix '-related', where 'tongue' refers to the muscular organ in the mouth and '-related' indicates a connection or association.

'tongue' changed from the Old English word 'tunge' and eventually became the modern English word 'tongue'.

Initially, 'tongue' referred to the physical organ, but over time, it evolved to include meanings related to language and speech.
