/ˈblʌdˌθɪnɪŋ/
reduce blood clotting
Etymology
'blood-thinning' is a compound formed from the noun 'blood' and the present-participle form 'thinning' of the adjective/verb 'thin'. 'blood' originates from Old English 'blōd' meaning 'blood', and 'thin' originates from Old English 'þynne' meaning 'not thick' or 'slim'.
'blood' comes from Old English 'blōd' and remained relatively stable in form and meaning; 'thin' comes from Old English 'þynne' (from Proto-Germanic *þunnaz). The compound 'blood-thinning' developed in modern English by combining 'blood' + the participle 'thinning' to describe an action or property affecting blood.
Initially the components meant 'blood' and 'not thick'; over time the compound 'blood-thinning' came to be used specifically in medical and colloquial contexts to mean 'causing reduced clotting or lower blood viscosity'.
