Parth+bain, & what is Vineyard?

I'm completely confounded on how these two would even combine, let alone in what order or how they'd mutate.

Parth = field, enclosed grassland, sward, *meadow

Bain = beautiful; good, wholesome, favorable; fair, fair-haired

In the interest of not making a million posts, is there even a term for "wine" or "vine" or "vineyard"? I'm trying to come up with a name for an elf from Dorwinion.

"laeg + calen... Laegalen, maybe? I'm not sure about this one."

Aren't laeg and calen both adjectives? If so would they compound?

It's no different than Iarwain in this regard.
