A língua, não surpreendentemente, é inteiramente equiparada ao (resto do) mundo quotidiano, como fundamentalmente instituída e determinada por normas conformistas.
Language, not surprisingly, is entirely on a par with the (rest of the) everyday world, as fundamentally instituted and determined by conformist norms. This is one area, however, where recent “social practice” accounts are decidedly more sophisticated than Being and Time, so I rest with quoting two passages exhibiting the basic idea:
But signs are above all themselves equipment, whose specific equipmental character consists in indicating. . . . Indicating can be defined as a species of referral. (SZ 77)
and
(The referral nexus of) significance . . . harbors within itself the ontological condition for the possibility … (of disclosing) “signification,” on which are founded in t urn the possible being of word and language. (SZ 87; compare SZ 161)
The important point is that linguistic forms are understood as (special) equipment, and hence the word/object reference relations are just a special case of interequipmental referral relations—which suggests another slogan: all intentionality is instituted referral.
