Other forms: modifications

A modification is a change or alteration, usually to make something work better.

If you want to change something — in other words, modify it — you need to make a modification. Lots of things require modification, because they get older or just because they can be improved. A car needs modification — in the form of snow tires — to be ready for the winter. Computer programs need modification all the time, because of new products or viruses. When you think of the word modification, think "change."
