What does deterge mean?
To deterge is to cleanse a wound or sore, especially by wiping away dirt, pus, or dead tissue and applying an antiseptic so that healing can proceed. The word belongs chiefly to the vocabulary of surgery and older medical writing, where preparing a lesion properly was considered essential before treatment. A surgeon might, for example, deterge a laceration with saline solution before suturing it. Beyond medicine, deterge can occasionally mean simply to wash something clean, though this broader sense is uncommon today. Derived from the Latin tergere, 'to wipe,' it shares its root with 'terse,' which originally described language polished by rubbing. Because deterge is formal and technical, it rarely appears in casual conversation, but it remains a precise term in clinical contexts and a striking example of how English preserves Latinate vocabulary for specialised purposes.

Etymology of deterge
Deterge comes from the Latin detergere, formed from de- ('away') plus tergere ('to wipe'), hence literally 'to wipe away.' It entered English in the early modern period, when medical writing drew heavily on Latin terminology. Its Latin root also gave rise to 'terse' — originally meaning smooth or polished as if rubbed — and underlies 'detergent.'
