Define Jack-of-all-trades Meaning

The other definitions are wrong.
A Jack of all Trades is someone who is decent at everything, but not especially adept at any one thing.

A person who is skilled at a variety of different things, but not to the same level as a person who is specialised in one of these things.

a person who is good at many things but has no particular specialty (often with master of none at the end)

A term used to describe someone who knows a lot about many things, but, with the second tag "master of none" added it transforms into a derogatory phrase meant to emphasize how mastery of one skill is important for deeper knowledge.

However, one, oft forgotten tag is the third one: "is oftentimes better than a master of one". Instantly, the term reverses meaning, symbolizing how a person who knows a lot about many things that integrates their skills allows them to surpass even a master of one.

Interesting phrase, nonetheless.
