obl:ad
: oblique adjunct
obl is split in three subrelations: obl:ad, obl:comp, and obl:periph.
The obl:ad
relation is used for nominal adjuncts which are governed by their heads. For nominal adjuncts which are not governed we use obl:periph.
obl:ad
is used regardless of the presence of a preposition before the adjunct :
On the other hand, when the nominal element is not an adjunct but an argument we use obj if it’s a direct object, or obl:comp if the argument is introduced by a preposition.
obl:ad in other languages: [pcm]
