Watch for an unstressed vowel that is hard to hear.

Same family: decimal point, decimal place, decimate, decade, decimation. If you can spell one, the shared part carries to the others.

Where it comes from: “Decimal” comes from the Latin word “decimus,” meaning “tenth,” from “decem,” meaning “ten.” It originally referred to dividing something into ten parts, which is why our decimal system is based on powers of ten.
