The difference between knowledge and wisdom.

What is the difference between knowledge and wisdom?

No need to get all deep and philosophical. Wisdom is knowledge coupled with good judgement. Simple as that.

Oxford defines knowledge as:

'knowledge /ˈnɒlɪdʒ /
▸ noun [mass noun]
1 facts, information, and skills acquired through experience or education; the theoretical or practical understanding of a subject:
a thirst for knowledge
her considerable knowledge of antiques.
▪ the sum of what is known:
the transmission of knowledge.
▪ information held on a computer system.
▪ Philosophy true, justified belief; certain understanding, as opposed to opinion.
2 awareness or familiarity gained by experience of a fact or situation:
the programme had been developed without his knowledge
he denied all knowledge of the incidents.
3 archaic sexual intercourse.
– PHRASES
come to someone's knowledge
become known to someone.
to (the best of) someone's knowledge
as far as someone knows; judging from the information someone has:
the text is free of factual errors, to the best of my knowledge.
– ORIGIN Middle English (originally as a verb in the sense ‘acknowledge, recognize’, later as a noun): from an Old English compound based on cnāwan (see know).'

And wisdom as:

'wisdom /ˈwɪzdəm /
▸ noun [mass noun] the quality of having experience, knowledge, and good judgement; the quality of being wise:

▪ the fact of being based on sensible or wise thinking:

– PHRASES

used ironically to suggest that someone's action is not well judged:

– ORIGIN Old Englishwīsdōm (see wise1, -dom).'

Then, there is the difference between being wise and being knowledgeable, again, I quote from Oxford:

'wise1 /wʌɪz /

be none (or not any) the wiser
not understand something, even though it has been explained:
she said an awful lot but he wasn't any the wiser
I am still none the wiser about the meaning of the word.
– ORIGIN Old Englishwīs, of Germanic origin; related to Dutch wijs and German weise, also to wit2.'

'knowledgeable /ˈnɒlɪdʒəb(ə)l / (also knowledgable)
▸ adjective intelligent and well informed:
