Words containing "ept":
* Adept: Skilled at something.
* Inept: Lacking skill or ability.
* Accept: To receive willingly. (Note: This one is a bit tricky as it doesn't directly relate to skill, but it shares the same root.)
* Except: To exclude or leave out. (Similar to "accept," it shares the root but doesn't directly mean "skilled").
* Concept: An idea or abstract notion. (Again, while it shares the root, it doesn't directly relate to skill.)
Other less common words:
* Ept: (archaic) Skilled; fit; apt.
* Eptness: (archaic) Skill; fitness.
It's worth noting that the root "ept" isn't as commonly used in modern English as some other roots. You're more likely to see the "ept" root in words that have been around for a long time, like "adept" and "inept."
