zip

a code of letters and digits added to a postal address to aid in the sorting of mail

a fastener for locking together two toothed edges by means of a sliding tab

forceful exertion

he plays tennis with great energy

he's full of zip

a quantity of no importance

it looked like nothing I had ever seen before

reduced to nil all the work we had done

close with a zipper

Zip up your jacket--it's cold

move very fast

The runner zipped past us at breakneck speed
