To swap is to exchange one thing for another. Swapping is a form of barter, and is now common online. Swapping is a way of exchanging goods where both parties obtain what they want. The nature of a swap is based on swappers perceived values of the items being exchanged. Idiomatically, the word is used as a comparison of values.
Examples of Swap:
|John's just too much of a swot for me.|
Sorry, I really do have to go and swot for this exam.
The amount of swotting I had to do for that test was absurd.
I really should swot up on my skills.
