Why "is" instead of "agus"?
The way was put to me is that "is" is generally used for things that are familiar or similar, "agus" is for things that could be disparate.
Hmm... I would like to know, too. I saw somewhere that is and 's are just contractions of agus, so would like to know which explanation is correct.
In general, I don't think either is wrong.
I second the first coment... is vs agus unclear...
We see two names combind with a agus all the time why now "is"
Is is simply a shortened form of agus, used when things are similar something like we might say in English salt 'n pepper or sweet 'n sour
