The semblative case (abbreviated SEMBL) is a grammatical case that denotes the similarity of one entity to another.
Wagiman, an indigenous Australian language, has a semblative case suffix -yiga, that is functionally identical to the -like suffix in English, as in the example: gahanthatmaminwhite mandup-pasit-ASPga-yu3SG-bejilimakkun-yigawoman-SEMBLgahan mamin dup-pa ga-yu jilimakkun-yigathat {white man} sit-ASP 3SG-be woman-SEMBLThat white man sits like a womanIn Warlpiri, the semblative case can be a semantic case, i.e., it can be semantically richer and less dependent on the verb.
In the example below, the -piya ('like') suffix can act as the main predicate and can attach to a demonstrative, suggesting that it is not purely a derivational affix.

As in many other languages, semblativity in English is marked with derivational affixes instead of being an inflectional case.
