How can I forget? You and Patruus helped me locate the raw text of L&S
which has since been so useful to me. It's my hope I find you in Elysium
some day to thank you personally.
I happened to stumble upon the dissertation of F. Skutsch, _De nominum
latinorum compositione quaestiones selectae_. He first lists three
compounds he believes are truly coordinative: suovetaur-ilis,
scytalosagittipelli-ger, and strufert-arii. Then he confirms with these
eloquent words what I had been thinking:
"Nemo sibi persuadebit hominem Romanum unquam talia dixisse, qualia
secundum indicas horum compositorum leges expectamus: *suovitaurum sive
*scytalosagittipelles. Elucet igitur nisi apposito sive suffixo sive
altero compositionis membro, quale est illud -ger, fieri non potuisse,
ut Romani compositum copulativum effingeret.
"Et in hac re summa inter indica et latina composita differentia inest:
nempe latinorum unitas semper ita tantum valet, si ad tertiam quartamve
notionem referuntur, quare non *strufertum dicitur, sed strufertarius is
qui strue et ferto sacrificat. [...] Nullum igitur in lingua latina
invenitur vocabulum quod Indorum dvandvicis satis apte respondeat."
My poor and very loose translation:
No one can be convinced that a Roman ever said such things as we might
expect according to the Sanskrit rules of these [the aforementioned]
compounds: *suovitaurum, *scytalosagittipelles. It is clear therefore
that without an apposited, suffixed, or other element of composition,
such as -ger, it was not possible for the Roman geist to form a
copulative compound.
Moreover, in this we find the main difference between Sanskrit and Latin
compounds, namely: [compositorum] latinorum unitas semper ita tantum
valet, si ad tertiam quartamve notionem referuntur.* Hence, the ritual
offerer of strues and ferta is called not a *strufertum but a
strufertarius. [...] Therefore there is not found in Latin a word that
aptly corresponds to the Sanskrit dvandvas.
*An awkward way of saying that whatever collective is indicated by the
term must be referred to a third or fourth morpheme that is part of the
compound, such as "strues fertumque" are referred to a doer indicated by
the suffix -arius in strufertarius.
