This is a bit tricky because "tence" isn't a standalone word, but rather a part of several words like "intense", "attendance", and "pretense".
Here's why:
* "Ten" is the root meaning "to hold" or "to stretch".
* "Tence" usually appears as a suffix, meaning "the state of being held or stretched".
So, while "tence" doesn't have a prefix in the traditional sense, "ten" is the core element that gives it its meaning.
