I do not understand the next sentence:
The term "studio apartment" is one used frequently by British estate agents to describe a small unit of accomodation.
First: Can someone explain to me why the adverb of frequency is placed after the verb "to use"?
The term "studio apartment" is one frequently used by British estate agents to describe a small unit of accomodation. *
Second, Can someone explain to me the meaning of "one" in this sentence?
Studio apartment is one of the terms frequently used by.... (It is the sentence that has sense to me)
Thanks in advance.
