Reconstruction:Proto-Germanic/-anē

Etymology
Possibly from a, which would also be the source of 🇨🇬 and possibly 🇨🇬. The final vowel itself is uncertain; it is usually given as based on the possibly related forms above.

The first vowel might not have originally been part of the suffix at all, possibly being detached from the forms the suffix was attached to; but it is usually found as such in Germanic languages.
