Origin of increase

First recorded in 1370–1395; Middle English incresen, encresen, from Anglo-French encres-, Middle French encreis(s)-, stem of encreistre, from Latin incrēscere, equivalent to in- in- ² + crēscere “to grow”; see crescent

However it's used, it refers to something that has gotten bigger. Anything that can add on can increase. You can increase your speed to go faster, increase your strength by working out, increase your knowledge by studying, and increase your circle of friends by meeting more people. You can work harder to see an increase of profits, and you can prevent an increase in your electric bill by turning out unnecessary lights.
