Equivalent to con- + nūbō (“I marry”) + -ium. Per De Vaan, the cō-n- (found also in other words that are on the surface composed of con- + a stem starting with n-) has been explained as a development from previous *com-sn-. Weiss reconstructs the word as going back to an original form *kon-snoubii̯om. It is not simple to determine the usual length of the vowel in the second syllable using poetic evidence (see below). Long ū would be the regular outcome of a diphthong derived from the e- or o-grade of the Proto-Indo-European root (and would get analogical support from the long ū in nūbō); on the other hand, the related words prōnuba and innuba can be cited to support the possibility of a pronunciation with short /u/, which would come from the zero grade of the Proto-Indo-European root.
cōnū̆bium n (genitive cōnū̆biī or cōnū̆bī); second declension
