Etymology
Etymology Information

'retrorse' originates from Latin, specifically the word 'retrorsus', where 're-' meant 'back' and 'torsus' (from the past participle of 'torquere') meant 'twisted'.

Historical Evolution

'retrorse' comes from Latin 'retrorsus' (literally 'turned back'); it entered scientific/technical English from Late Latin/Neo-Latin usage and has been used in English chiefly in botanical and zoological descriptions.

Meaning Changes

Initially it meant 'turned back' in literal Latin usage, and over time this literal sense has been retained in English, especially in technical descriptions of plant and animal parts as 'pointing or bent backward.'
