Spanish: conjugation of obsolete verbs

[El Ganador]

I'm not sure whether this question is apt here, so please correct me if it isn't.

Is there any website that tells the conjugations of obsolete verbs in Spanish? The DLE doesn't tell conjugations of obsolete verbs, so is there any other site?

Hello. For ex. you can enter reman* in RAE's CORDE, with 1200 - 1300 in Cronológico. Then you see both remanga and remanezca (remain.sᴜʙᴊ.3sɢ, for remanir & remanecer), which appear in different books: Roudil et al. 2001, Cahiers de Linguistique; Catón 1999, Index Verborum; Rodríguez 1998, Diccionario de conjugación; Malkiel 1973, Romance Philology 26; Romera-Navarro 1951, Registro de lexicografía hispánica; Boggs 1946, Tentative Dictionary of Medieval Spanish; Grases 1942, Acerca del grupo zc; Oelschläger 1937, A Preliminary Spanish Word-List; Nercasseau, Hanssen 1905, Antología castellana arcaica; Grassner 1897, Das altspanische Verbum.

Generally for 'Old Spanish,' a form may reflect more 'Leonese' or 'Aragonese' traits, i.e. you go with the 2nd or 4th line, depending on authors or time. For ex. *zrá, *zdrá, *zdra in the Vidal Mayor or Fuero Navarra, Berceo or the Alexandre, all for 'Aragonese.' Also *ndrá shared with Berceo, etc. Then Cast. tendrá, Port. terá; OFr. tendra, Oc. tendrà, OFr. vendra, Oc. vendrà. For your other thread, notice remanga in Mio Cid agrees with It. rimango, rimanga, but remandrán with OFr. remandra, remandront.
