e/Kluge's Law

Information
has gloss	eng: Kluge's Law is a Proto-Germanic sound law formulated by Friedrich Kluge. It describes the assimilation of an n to a preceding voiced consonant, under the condition that the n was part of a suffix which was accented in Proto-Indo-European (PIE). This law explains the origin of the Proto Germanic geminates kk, tt and *pp. Even though Kluge does not claim to have originally discovered the phenomenon, it is still named after him, because he provided the canonical formulation of the sound law.
