Choosing -ed or -ing is sometimes a difficult question for me.
In this sentence:
The dog is running.
I have a noun phrase: the running dog.
Or in this sentence:
The shop is closed.
I have the closed shop.
I think it is about past and present participles being used as (attributive) adjectives.
However, when I ran into the case of complicated, I found out that it can be used in different ways and have different meanings:
the complicated question
the complicating question
The first one means:
the question that makes people feel complicated or confused
The second one means:
the question that makes something like the process or the investigation complicated
For most answers I found on Google, complicated is mainly used, while complicating is only used in some particular cases.
One way to explain this problem is that some -ed adjectives have a certain meaning or usage that is widely used; therefore, English users use complicated instead of complicating just because of its meaning, without realizing that the word can be used with both -ed or -ing because of its verbal root.
By using the term, I am not sure whether or not I use the right one. I just want to say that both complicated and complicating have origniated from the verb complicate.
- Am I correct?
- Is there any other way to explain the case?
