-ed and -ing adjectives: bored or boring?
The rule in short
Bored or boring, interested or interesting: the -ed form says how a person feels, the -ing form says what causes the feeling. With the typical mistakes and how to pronounce the -ed ending.
Most pairs come from a verb that means "give someone a feeling": bore, interest, excite, worry. Add -ed or -ing with the normal spelling rules: surprise → surprised, surprising; worry → worried, worrying.
| Verb | -ed: how someone feels | -ing: what causes the feeling |
|---|---|---|
| bore | bored | boring |
| interest | interested | interesting |
| tire | tired | tiring |
| excite | excited | exciting |
| surprise | surprised | surprising |
| worry | worried | worrying |
| embarrass | embarrassed | embarrassing |
| confuse | confused | confusing |
| disappoint | disappointed | disappointing |
| annoy | annoyed | annoying |
| frighten | frightened | frightening |
| relax | relaxed | relaxing |
Both forms can stand before a noun (a tiring day, a worried mother) or after verbs like be, feel, look, seem and get (I get bored easily).
Things usually take -ing. A book, a film, a job or the news cannot feel anything, so they are interesting, not interested. Some -ed adjectives can also describe things that show a person's feeling or the mood of a time or place: a worried look, a surprised voice, a relaxed evening.
People can be both, with different meanings. Tom is bored means Tom feels it: he has nothing to do. Tom is boring means other people feel it when they are with him. So I'm boring is not a way to say that you have nothing to do; it is a rather unkind thing to say about yourself. In the same way, Anna is interesting means people enjoy talking to her, while Anna is interested usually needs a topic: interested in history.
Small words after the -ed form. Many -ed adjectives take a preposition before the cause: interested in, worried about, excited about, frightened of, bored with. Note tired of, which means you no longer want something: I'm tired of the rain.
Pairs that break the pattern. A few feelings have a different word for the cause. You feel scared, and a film is scary (scaring is only a verb form: you're scaring me). Frightened and frightening follow the normal pattern and mean almost the same, so scared and frightened are both fine for the person. You feel pleased; for the thing, English normally says pleasant or nice (pleasing exists but is much less common).
Pronunciation. The -ed of these adjectives follows the same rule as regular past forms: an extra syllable /ɪd/ only after /t/ or /d/ (interested, excited, disappointed), otherwise just /d/ (bored, tired, worried) or /t/ (relaxed, embarrassed). The lesson on -s and -ed endings has the full rule.
