"it's curious that you got your e-mail for me back"
I would like to explain to my student (above ) that this doesn't sound right!
Can I say to use 'curious' you need to have a noun as reference e.g. to be curious about something/someone OR to be a curious kind of person.....
In English we would say it's odd that.....OR how strange that......OR EVEN isn't it funny that......
Am I correct?!
No, you can say this (though I presume it should be "e-mail from me").
It means strange; unusual:
It's curious that Jo did not finish her letter to Bob.
It is curious that the dog did not bark when the doorbell rang.
