dere.

Principally from eastern dialectal Norwegian der, dere, object form of de (/di, de/, “you”). This latter is from Middle Norwegian ther, *thi, from Old Norse þér, *þīʀ, þit, themselves from ér, īʀ, it (see these) with initial þ- by rebracketing of the conjugational suffix -ið of preceding verbs. By analogy, the same onset was given to the object form yðr, iðr, yielding *þyðr, *þiðr, whence the before-mentioned der(e), also dør(e). Generalization of the object form of plural pronouns is found in various Norwegian dialects. At the same time, interaction with the third-person plural forms is likely, particularly under influence of Dano-Norwegian de (“they”), deres (“their”), which were also used as polite second-person pronouns (see De). In the Dano-Norwegian vernacular, the form dere may have established itself in part by backformation from Deres (“your”).
