agglutinating language
Definition - A type of synthetic language that uses agglutination to create words, i.e. words are formed by concatenating morphemes that represent units of meaning such as diminutive, past tense, and plural, e.g. the Turkish word ev-ler-de (house plural in), which means "in the houses."

Etymology -
The term derives from the Latin agglutinationem, fasten with glue (from ad, to + glutinare, to glue). It was introduced by Wilhelm von Humboldt in 1836 to classify languages according to their morphology.

Oxford English Dictionary -
Its first citation is from 1830:
"The Ober-Deutsch was fuller and fonder of agglutinating words together."
(Coleridge Table Talk (1851) 67)
