expl: expletive: reflexive pronoun with an inherently reflexive verb
Reflexive pronouns (see the feature Reflex) usually replace objects of verbs. However, some verbs are inherently reflexive, i.e. the verb always occurs with a reflexive prounoun, and the pronoun cannot be replaced by a non-reflexive pronoun.
With these verbs, the reflexive pronoun is attached as expl instead of dobj.
(Note that the expl relation is first used for this purpose in the UD release 1.2,
to increase parallelism with other languages. In the previous releases this usage of
reflexive se/si was labeled compound:reflex.)
