JACK
OF ALL TRADES |
a person who knows a little about a lot of different
subjects or activities, but not a lot about any one of them
The expression is part of the saying “He’s a jack of all
trades but a master of none.” Being described as a jack of
all trades can be either a compliment (usually when it is
used without the second half of the saying) or an insult
(when it occurs in the saying and the emphasis is on the
fact that one is master of none). |

and wiring in his house, he fixed his roof when it leaked,

when it needs it. He’s really a jack of all trades.
2. The position in the company required someone who knew
everything about a very narrow subject. They weren’t looking
