hate: [OE] There are indications that the ancestral meaning of hate may have been a neutral ‘strong feeling’ rather than the positive ‘dislike’. It has been traced to a prehistoric Indo-European *kə des-, amongst whose other descendants were Greek kedos, which meant ‘care, anxiety, grief’, and Old Irish caiss, which meant ‘love’ as well as ‘hate’.

It is clear, though, that the notion of strong dislike became established fairly early, and that it was certainly the sense transmitted via Germanic *khatis-, source of German hass, Dutch haat, Swedish hat, Danish had, and English hate. The derivative hatred was formed from the verb in the 13th century with the suffix -red ‘condition’, as in kindred.

Old French borrowed the Germanic verb *khatjan ‘hate’ as haïr, and derived from it the adjective haïneus, acquired by English as heinous [14].
