Thanks for your question
TorGmatGod!
The words "excepting" and "excepted" are rarely ever used in modern English. So rarely, in fact, we had to look them up just to be sure they were actually words.
The word "excepting" can be used in place of the phrase "except for" or "apart from" in some cases. However, using "excepting for" is not correct - you'd just use "excepting." Here's an example:
I enjoyed the entire 8-course meal,
except for the seaweed salad. -->
OKAYI enjoyed the entire 8-course meal,
excepting the seaweed salad. -->
OKAYI enjoyed the entire 8-course meal,
excepting for the seaweed salad. -->
WRONGThe word "excepted" can be use as a replacement for the words "excluding," "excluded," or "except for." It's used after you refer to a person or thing to show that they/it are not included in the group you're talking about.
Students are expected to study every night for 2-3 hours, weekends excepted. --> OKAY
I hope that helps! We enjoyed the challenge on this one!
