Just curious, sometimes I notice we say things like "A group is 2 eggs".
Then we might say "I have 3 groups".
Why don't we ever say it as " I have 3 (2 eggs)s" instead of "i have 3 groups". Really, the 2 eggs is referring to the same grouping. I take it we just don't say it that way since it is confusing and wordy? Just a dumb thought, thanks for the help
You have not defined the context in which this is used. There may be several groups, consisting of various objects/items, in this case one of which is two eggs.
