Forms
tantundem n (indeclinable)[1] It is the neuter of tantusdem, tantadem “just as great”; the genitive tantīdem means at the same price.[2][3] It is also spelled tantumdem.[2][4]
Etymology
It is from Latin tantus (“so great”) + -dem, with the suffix of īdem.[2] Wiktionary explains the ⟨n⟩ as the ⟨m⟩ of tantum assimilated to the following ⟨d⟩.[1]
Earliest recorded meaning
Köbler dates it from Plautus,[5] who uses it as an adjective, I'll try just as great a trick, and as a noun, you will get just as much.[2]
Semantic evolution
As an adjective it is just as great or as much, which is rare: Livy says nearly as many citizens and allies fell, and jurists use it of a sum of money.[2][3] As a neuter noun, its common use, it is the same quantity, just as much: Cicero wants as much given to magistrates as always, Horace has as much drawn from a small store, and Livy gives the allies as much as the soldiers.[2][3] Seneca contrasts repaying the same thing with repaying the same amount.[2] The genitive tantīdem is at the same price or worth, as Ennius' dog barking without teeth, and tantundem est means it comes to the same thing: in Terence one asks whose a girl is and where she is from and gets the same answer.[2] As an adverb it is to the same degree, just as much: Caesar has a rampart just as wide.[2]
