See the etymology of the corresponding lemma form.
This template can be used in the etymology sections of non-lemma forms, to indicate that they are inflections that are not missing a more complete etymology. It is mainly used in entries with multiple etymology sections in which one or more sections is a lemma. In most other cases, adding an etymology to regular non-lemma forms is considered unnecessary per Wiktionary:Etymology. See also Wiktionary:Beer parlour/2016/March#Etymology section for non-lemmas.
