Reconstruction:Proto-Germanic/fergunją

Etymology
From, from , or from. The former possibility would have an unexplained irregular development of w > g in Germanic, while the latter matches in form but poses difficulties in the meaning.

The existence in Old Norse of a masculine noun (ostensibly from ) alongside the feminine noun  (from ) and the neuter, whose original meaning in Proto-Germanic can be reconstructed as “(forested) mountain(land)”, suggests that the underlying term was a Proto-Germanic adjective, probably cognate with 🇨🇬 (presumably originally an appellative meaning “forested (mountain)land”), also apparently originally an adjective (compare the Gallo-Latin adjective found in  alongside ), which in both cases can be reconstructed as meaning “forested”. The suggested derivation from fits this well and suggests an original meaning “covered in oaks” for, rather than a noun meaning “forest”.

Noun
