obl:unmarked: adpositionless oblique

This relation is a subtype of the obl relation that applies when an oblique takes the form of a nominal lacking a preposition (a.k.a. a noun phrase). It is “unmarked” in that, unlike most obliques, it has no adposition.

obl:unmarked merges two older subtypes, obl:npmod and obl:tmod. It has a nominal-level counterpart: nmod:unmarked.

Examples include:

(i) a time, manner, or extent adverbial in a clause
