Borrowed from Danish harmonium, from Latin harmonium, a pseudo-Latin trade name coined from harmonie (“harmony”).
harmóníum n (genitive singular harmóníums, nominative plural harmóníum)
The word may be declined according to the regular paradigm for strong neuter nouns:
singular | plural | |||
---|---|---|---|---|
indefinite | definite | indefinite | definite | |
nominative | harmóníum | harmóníumið | harmóníum | harmóníumin |
accusative | harmóníum | harmóníumið | harmóníum | harmóníumin |
dative | harmóníumi | harmóníuminu | harmóníumum | harmóníumunum |
genitive | harmóníums | harmóníumsins | harmóníuma | harmóníumanna |
However, the dative and genitive plural forms are awkward in pronunciation, and seem to be generally avoided; those forms are not attested.
A dative singular harmóníum (or harmoníum) is attested, and also other variations, such as a Latinate plural harmónía, and forms that drop the -um upon the addition of native inflectional endings or the appended article (as is the norm in Danish): harmóníið, harmóníi, harmóníinu.
