Reconstruction:Proto-Germanic/hrīmô

Etymology
According to Kroonen, the nominative stem originally had a root-final -f, which was lost before the m of the mn-stem endings. This in turn stems from an older root-final -p. In the oblique stems, however, the m was lost instead, making the resulting -pn- cluster vulnerable to, which transformed it into a geminate -pp-. This geminate was then shortened due to a heavy long-vowel syllable preceding it.

Pokorny derived this from. Kroonen instead reconstructs a root *kreyp-.

Noun

Inflection
According to Kroonen, this was an irregular mn-stem noun, displaying apparent consonant alternation between m in the nominative stem and p in oblique stems.
