For Sumerian, the equative was formed by adding the suffix -gin7 to the end of a noun phrase:
- lugal, "king"; lugal-gin7, "kinglike", "like a king":
- nitah-kalaga; "mighty man"; nitah-kalaga-gin7, "like a mighty man"
For Ossetic it is formed by the ending -ау [aw]:
- фæт, "arrow"; фæтау, "arrowlike"
- Ницы фенæгау йæхи акодта, lit. "nothingseer-like himself made" ("[he or she] pretended to see nothing").
Welsh, though it has no equative case of nouns, has an equative degree of adjectives.
Sireniki Eskimo had an equative (or comparative) case for describing similarities between nouns.
Finnish has the derivational suffixes -mainen and -lainen that have the same meaning, but form new words rather than functioning as grammatical case suffixes. For example, kuningas ~ kuningasmainen "king ~ kinglike".
