catch on the hop

[Diafana]

Hello,

Would someone be able to shed some light on the origins of the idiomatic expression "to catch on the hop"? Is it a sporting metaphor?

Many thanks,

Diafana

I don't think it's an idiom. The only use I can think of it is quite literal, from the sport of baseball.

Thanks for your input but it is actually an idiom in BrE:

catch somebody on the hop
if you catch someone on the hop, you do something when they are not ready for it and may not be able to deal with it.
Examples: Well I'm afraid you've caught me on the hop - I wasn't expecting your call until this afternoon. If we attack at the very start of the game, we may just catch their defenders on the hop.

I have never heard of it. Not a lot of people going out to pick wild hops these days.

Thank you very much for your help, 5jj, much appreciated!

Your link seems to go to a school with a Chinese connection. "Catch on the hop", could be an idiom, but I have never heard of it before.

As Diafana said, 'catch somebody on the hop' is an idiom in BrE. I am not at all sure about the origin suggested in the link I gave. It sounds a bit like folk etymology to me, but I haven't been able to find anything more convincing.

The only reasoning I can come up with for it is that when you have both feet planted on the ground, you are balanced and even and ready to move in any direction.

If you are hopping, you are off-balance (probably), not completely connected to the ground and therefore can be caught off-guard.

It also makes me think of the phrase "to catch somebody on the back foot" which has much the same meaning, to catch them (metaphorically) off-balance or by surprise.

If you are hopping, you are off-balance (probably), not completely connected to the ground and therefore can be caught off-guard.

That sounds more likely to me than the Kentish hop-field tale. But that's only my feeling.

ps, The OED gives examples of 'catch/take on the hop' under the 'act of hopping' (jumping on one leg) definition of the noun.
