From Middle English -st; see -est.


The suffix -st consists of two parts: a suffix -t (Proto-Indo-European *-ti) and an inserted -s-. The -s- is the result of a wrong segmentation of stem and suffix of a noun in cases where the stem of the noun ended with -s-. For example: a word like Dutch vorst (β€œfrost”) could be interpreted as vors+t or as vor+st. This suffix existed already in Gothic (πŒ°πŒ½πƒπ„πƒ (ansts), from 𐌿𐌽𐌽𐌰𐌽 (unnan)).



It was formed from -s (adjective-forming suffix) + -t (adverbial suffix) in the Old Hungarian period. The adverbial sense of the suffix -t can be shown only in this -st morpheme.


Middle Dutch

From Old Dutch -ist, -ost, from Proto-Germanic *-istaz, *-ōstaz.
