About でもある

As an extension of the formal version of the auxiliary verb だ, である, でもある simply conveys that something 'is also (B)'. However, as も often shows something that is surprising or unexpected, でもある will primarily be used to describe additional facts about (A) that may be unexpected. Due to this, でもある usually fills the (B) role in sentences like 'while (A), it is also (B)', or 'in spite of (A), it is also (B)'.
でもある may be used after nouns, or な-Adjectives.

    If that’s the case, shouldn’t the 硬 symbol be on this grammar point?

  • Daru


    Part of literary style, not exclusively! That’s why it doesn’t have the 硬.

    I’ve heard Japanese people say でもある in conversation. A teacher once told me: ‘日本人でもある私にも意味が変わらない’ When reading Murakami. It made me laugh.

  • simias


    It’s very tangential but this point just now made me understand that だ is ultimately a contraction of である. である → であ → だ. Hence だった → でもあった. It’s obvious in hindsight but I don’t remember ever seeing it pointed out in the resources I’ve used.

    Mind blown.
