Noun Case > Non-Core Grammatical > Contrastive Case (CONTR)
The contrastive case, in short, draws a contrastive comparison with the subject. It topicalizes a noun, about which a statement is then uttered about a different noun (the subject) which is implied to be a thing with which the contrastive noun shares little or no commonality. Unlike the adverbial case -jat, which can draw attention to similarities, the contrastive case draws attention to differences.
It can typically be translated into English as as compared to, or as contrasted by, or simply than.
The contrastive case stands out from all the other cases in that its epenthetic sandhi vowel does not come at the beginning of the morpheme. It is still triggered by the same conditions that would trigger it were it at the beginning like the other case endings. Phonologically, the epenthetic e of this morpheme behaves as though it were at a morpheme boundary, which means that when it is included, this case is pronounced with three syllables: [jaˈɛtː.ɐ].
The contrastive case ending is -jaetta.
The dog is [big] compared to the cat.
(Lit: dog‘bigdogis catcomparedto)
(Imp: As compared to the cat, the dog is a big dog)
