Editing Lake Peipus (section)

==Name==
The origin of the name ''Peipus'' ({{langx|et|Peipsi}}) is uncertain, although it may be paralleled by Lake Peipiä ({{langx|ru|Копанское озеро}}) and the village of Peipiä ({{langx|ru|Пейпия}}) along its shore, and by Peipozero ({{langx|ru|Пейпозеро}}) near [[Onega Bay]]. [[Paul Ariste]] suggested a pre-Finnic origin of the name, [[Julius Mägiste]] suggested a connection with ''peipo'' or ''peippu'' 'chaffinch' (or other songbird) or [[Votic language|Votic]] ''põippõ'' 'chicken', {{ill|Lauri Kettunen|et}} suggested derivation from a personal name, and {{ill|Rufʹ Aleksandrovna Ageeva|ru|Агеева, Руфь Александровна}} suggested a Baltic etymology, comparing it to Latvian ''piepe'' and Lithuanian ''pepis'' 'moisture, mold'.<ref name="DEPN">{{cite web |title=Peipsi järv |url=https://www.eki.ee/dict/knr/index.cgi?Q=Peipsi&F=M&C06=en |website=Dictionary of Estonian Place Names |publisher=Eesti Keele Instituut |access-date=December 15, 2023 |location=Tallinn}}</ref> The Russian name ''Chudskoye ozero'' (Чудское озеро) means 'Chud Lake' (i.e., 'Estonian Lake'); the ethnonym ''[[Chud]]'' ({{lang|ru|чудь}}) referred to various Finnic peoples in what is now Estonia, Karelia, and northwestern Russia.<ref name="DEPN"/>
