Once, Twice
Incorrect : I visited the place only one time or two times.
Correct : I visited the place only once or twice.
Note: The expressions "one time' and “two times” are not used. Instead, we use “once' and “twice'. But the word “thrice' for “three times' is out-dated. However, 'at one time” means "formerly'.
For example:
At one time they were very close friends.
"At one time” can also be replaced by "once'.
We can say:
Once they were very good friends.
