Student or Learner
I am going to go back to the school on August
and now I have to book my airplane ticket.
My English teacher in Korea said that on with bottom line in the sentence above should be changed to "in".
But in my mind, I think people usually put on before month. Which is correct?
Your teacher is correct, but if the date is included with the month, "on" is used, as "on August 25" or "on the 25th of August".
I have a good grasp on IN and ON with regard to physical location. e.g. ON a ship, IN the yard, ON the field.
But what about IN vs ON with money?
1. This will save $500 ON tes
2. This will save $500 IN testing.
... in testing fees.
... in travel expenses.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Thank you for the replies. So how would you write my sentence down? "This will save $500 __ in testing expenses."
I'd probably save $500 dollars in testing fees if I managed to reduce the fees I was paying, and on testing fees if I did not now pay any at all. However, I am not convinced that I'd give the same response next week; there may be no real difference.
