The present tense is I wot, thou wottest, he wot or wotteth, we wot  ; the past tense, I wist, he wist, ye wist  ; the infinitive, ‘to wit.’ In   2 Corinthians 8:1 occurs the phrase do to wit , i.e. make to know we do you to wit of the grace of God.’ The subst. ‘wit’ means in AV [Note: Authorized Version.] ‘knowledge’; it occurs only in   Psalms 107:27 ‘at their wit’s end.’ ‘Witty,’ which is found in   Proverbs 8:12 , Jdt 11:23 , Wis 8:19 , has the sense of ‘knowing,’ ‘skilful’; and ‘wittingly’ (  Genesis 48:14 ) is ‘knowingly.’
