do these sentences make sense:

we had to wean him off of seafood because we found out he was allergic to shellfish.

the team groused at frank for having to run 8 laps around the field.

Yes, but here are a couple of suggestions:

1. Capitalize the first letter of each sentence.

2. "wean him from" is correct, rather than "wean him off of"

OK?

=)

You also need to capitalize Frank. The word "eight" should be spelled out.

Yes, both sentences make sense grammatically and contextually.

In the first sentence, "we had to wean him off of seafood" means that someone had to gradually reduce or eliminate the consumption of seafood for him. This was necessary because they discovered that he had an allergy to shellfish.

In the second sentence, "the team groused at Frank for having to run 8 laps around the field" implies that Frank was being complained to or scolded by the team for being obligated to run 8 laps around the field. The word "groused" indicates that the team expressed dissatisfaction or annoyance towards Frank.
