"Know how" is a colloquialism. It means “the skills necessary to do a task”. It comes from the concept of knowing how to do something, which means having the “know how” to do something. Can John fix his truck? Yes I think he has the know how to do that. (Yes I think John has the skills to do that.) You would not use “know how” in a formal setting, like when you write a resume to get a job. But you might hear it in speech.

Joking example of "know-how" "Do you know how to fix this?" "No, how?"

It's probably worth also noting that the French phrase "savoir faire" - "to know (how) to do (something)" sometimes turns up in English. Since both languages have had a close relationship for centuries, phrases get borrowed or literally translated. As a result, you could read your phrase as "know how (to do...something)", even though you use it as a noun. Confusing, yes? So Froopy's example could also go thus: Can John fix his truck? Yes I think he has the 'savoir faire' (/know how) to do that. ...however, using foreign phrases in English speech usually gives an eloquent, florid, or formal feel to the sentence. "Yes I think he has the know-how..." does sound more friendly and common. (I realise my answer is tangential, but I think it's good to know a bit of background history with the basic definition...)

yep, it's basically "knowledge & skill" :)

Hello Heba, It could also mean: - ingenuity, aptitude, or skill; knack - commercial and saleable knowledge of how to do a particular thing; in the sense of experience. - a way of doing something, especially a systematic way; implies an orderly logical arrangement (usually in steps) - a supply of ways of accomplishing something.
