Etymology

O.E. moste, pt. of motan "have to, be able to," from P.Gmc. *motanan "to fix, allot, appoint, to have room, to be able" (cf. O.Fris. mota, M.L.G. moten, Du. moeten, Ger. müssen "to be obliged to," Goth. gamotan "to have room to, to be able to"), from PIE base *med- "to measure." Used as present tense from c.1300, from the custom of using past subjunctive as a moderate or polite form of the present. The noun meaning "something that has to be seen or experienced" is from 1892.
