Etymology
Origin of contraction
First recorded in 1400–50; late Middle English, from Old French, from Latin contractiōn-, stem of contractiō, equivalent to contract(us) “drawn together, restricted,” past participle of contrahere + -iōn- noun suffix; see contract, -ion
Explanation
A contraction is the act of decreasing the size of something or shortening it, or it can be the process of becoming smaller or compressed. The two most well-known uses of contraction involve muscles and words. A contraction of the muscle tenses it or shortens it, like when you're standing in the mirror flexing and admiring yourself. On the other hand, a contraction can also be two words that are combined, with a few letters often replaced by an apostrophe, like when we change do and not into don't.
