Free relatives
Free relative clauses are marked as ccomp, csubj, advcl and advcl, depending on their relation to their verbal or nominal head.
Comparatives
For basic comparative constructions, we connect nominal second terms of the comparison via a nmod relation.
We use the advcl relation for clausal elements.
