An archaic verb meaning 'to know' or 'to be aware of something.'
From Old English witan meaning 'to know,' related to German wissen and Dutch weten. This root also gives us 'wit,' 'wisdom,' and 'witness.' Largely obsolete except in dialectal use.
This tiny word is the ancestor of many modern English words about knowledge and intelligence! You can still hear echoes of 'wis' in phrases like 'to wit' meaning 'that is to say,' and it survives in some rural dialects where people might say 'I wis' instead of 'I know.'
