might: [OE] Might goes back ultimately to Indo- European *mag- ‘be able, have power’, the same base as produced the auxiliary verb may. The noun might was formed with the Germanic suffix *-tiz, which also gave German and Dutch macht ‘power’; and the verb might, the past form of may, contains the past inflectional suffix (in modern English -(e)d).
