Question 1

Which prepositions follow -ed adjectives?

Accepted Answer

Several common -ed adjectives are followed by regular preposition patterns. We usually say "interested in" a topic, "excited about" an event, "bored with" or "bored by" a situation, "frightened of" something general, and "disappointed with" a person or result. These patterns belong to the feeling adjective because they explain what the person feels about. The -ing adjective normally describes the cause directly: "an interesting topic", "an exciting event", "a boring situation", "a frightening noise", or "a disappointing result."

Question 2

Can one sentence use both -ed and -ing adjectives?

Accepted Answer

Yes, and this is very common. A sentence can name both the person who feels something and the thing that causes the feeling: "I was surprised by the surprising result." The first adjective, "surprised", describes the person. The second adjective, "surprising", describes the result. This pattern is useful because it shows the complete relationship between cause and reaction. In mixed exercises, read the whole sentence carefully because the two blanks may need different endings from the same adjective pair.

Question 3

Why do some -ing forms sound unnatural?

Accepted Answer

Not every verb forms a common -ing adjective in everyday English. For example, learners may expect "stressing" to describe a stressful situation, but native speakers usually say "stressful" instead. This module focuses on common, natural pairs such as boring/bored, interesting/interested, confusing/confused, exciting/excited, frightening/frightened, and satisfying/satisfied. When you learn a new pair, check real examples and common collocations. The meaning rule still helps, but vocabulary knowledge tells you which adjective forms are actually normal.
