Strong non-lemma forms
Fragment of a discussion from User talk:Rua
This practice doesn't seem to be the best approach for arbitrary, memorized strong forms like these. It is understandable for forms like "walked" to leave the etymology to "walk", but in the cases of forms like "brought", "did", "sang", where the etymology of the particular form can be independently traced back to earlier forms, this information should be more readily accessible from and noted in the non-lemma form's page.
