Same family: surely, unsure, assured, certain, confidence. If you can spell one, the shared part carries to the others.

Where it comes from: “Sure” comes from Old French “seur” or “sor,” which came from Latin “securus,” meaning “safe” or “without care.” Over time, the meaning shifted from “safe” to “certain” or “without doubt,” which is how we use it today.
