Participle Adjectives: -ed vs -ing
Feelings (person) vs Cause (thing) No practice — theory only

What are participle adjectives?

Many verbs of feeling or reaction (amuse, annoy, bore, confuse, excite, interest, surprise, tire, worry…) form two adjectives:

  • -ed form = how someone feelsI’m bored.
  • -ing form = what causes the feelingThe film is boring.

A quick test: If you can add by it after the adjective (I’m bored by it), it’s usually the -ed form. If you can add to watch/see/hear (It’s boring to watch), it’s the -ing form.

Form & placement

  • Predicative after linking verbs (be, feel, seem, look, sound): She looks tired. The talk sounded interesting.
  • Attributive before a noun: an exciting match, a bored audience.
  • Change of state with get/become: We got annoyed quickly.

Although -ed adjectives typically describe people/animals, they can modify things if a human reaction is implied: a tired idea (metaphor), a crowded train (past-participle result).

Degree words that collocate well

  • Gradable use very/really/quite: very boring, really interested, quite worrying.
  • Non-gradable/extreme prefer absolutely/completely/utterly: absolutely terrified, completely exhausted, utterly amazed (not *very terrified*).
  • So for emphasis: so exciting, so bored. Such + (a) + adj + noun: such a boring lecture.
