Metangender (metanagender or metaagender/meta-agender): being beyond agender; something beyond genderlessness; an experience or a gender identity beyond agender. Not automatically antiagender, allogender/alogender or alloagender/anallogender (aloagender/analogender).

Different from supranagender (suprangender/superagender), this isn't necessarily atop, above, over, besides, or superiorly, but not essentially inferiorly (infranagender/aninfragender), below, under, or inside, it's aside, outside, or sideway. Like ecto-, extra-, or exo- prefixes (ectoagender/ectagender, exoagender, extranagender/extrangender/exteragender).
