description: >-
Past participle as adverbial clause modifier. Excludes WHIZ deletions
(which use acl relation), passives (which use aux:pass relation), and
perfect aspect (which uses aux relation).
- source: pybiber
requires:
- pos
- dep
cql: '[dep="punct"] [pos="VBN" & dep="advcl|ccomp"]'
description: >-
VBN with dep advcl or ccomp, preceded by punctuation. Same logic as
[[VBG_CLAUSE]]: pybiber requires a comma or other punctuation
immediately before the participle as a clause boundary marker.
examples:
- text: _Exhausted_ by the journey, Frodo rested
- text: the road _taken_
- text: These include cancers _caused_ by viruses.
