For Explanation Examples For is used to express how long something or someone has been doing something. For is used to state a period of time and is usually used with a noun or a pronoun. We waited for an hour outside the theatre for you. Curtis has been riding his bicycle for two hours.

Rosie, my dog, has been barking for a long time. The traffic has been bad for the last five years. I think it's like this: 1. I lived in Seoul for two years during which time I enjoyed the city. The Korean war, during which many people were killed, ended in You can't use "during which time" in the second sentence because your remark doesn't apply directly to a period of time unlike in the first sentence where we are talking about two years but to a war.

We know the war lasted for some specific period of time BUT we're not mentioning it in the sentence. All these sentences need at least one comma. The second two need two commas each.

Which can be either a relative pronoun or a relative adjective. In 1a and 2a, it is a pronoun and presumably refers to the noun just before it two years, the Korean War. In 1b, which time refers back to when "I" lived in Seoul. In 2b, which time refers to the Korean War, but the word time seems to distract, rather than help, the reader. Does "during which" mean "during that time" in the sentences in post 1?

If so, is this meaning applicable to all situations? Click to expand Thank you Parla. I got the point.
