Ετυμολογία (Αγγλικός)

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 (“frost”) could be interpreted as vors+t or as vor+st. This suffix existed already in Gothic (𐌰𐌽𐍃𐍄𐍃 (ansts), from 𐌿𐌽𐌽𐌰𐌽 (unnan)).
