@Jberkel, -sche: The etymology seems to be overly complicated. Is there any reason why it could not be just impfen + Neid? ←₰-→ Lingo Bingo Dingo (talk) 18:26, 1 May 2022 (UTC)
- I don't see why not, although similar forms tend to be noun + Neid, as Brotneid, Futterneid, Penisneid etc. – Jberkel 22:07, 1 May 2022 (UTC)
