Etymology
Etymology Information

'testes' originates from Latin, specifically the word 'testēs' (plural of 'testis'), where 'testis' meant 'witness'.

Historical Evolution

'testes' passed into English via Medieval/Scientific Latin (as 'testes') and entered modern English usage largely unchanged as the anatomical plural of 'testis'.

Meaning Changes

Initially Latin 'testis' primarily meant 'witness'; over time the term acquired or was used for the anatomical sense 'testicle' and the plural 'testes' came to denote the paired male reproductive organs in modern scientific and medical usage.
