dosed
UK[dəʊst]US[doʊst]
v
Past tense and past participle of 'dose': to give a measured amount of medicine to someone or something.
Etymology
The verb 'dose' originates from the French 'doser', meaning to determine or administer a portion. This, in turn, derives from the late Latin 'dosis', borrowed from the Greek 'dosis' (a giving, a portion), which comes from the verb 'didonai' (to give). The core semantic thread from Greek to modern English is the concept of a measured portion given, specifically for medicinal purposes. The '-ed' suffix is a common Germanic-derived inflection used to form the past tense and past participle of regular English verbs, attached to the borrowed base 'dose'.
