"The first letter of/for/in each month, such as June, July, etc., is big."
My was is taking online English classes right now. Yesterday, when he was taking a class, this question came to me.
I feel all three prepositions make sense. Which one sounds more natural? How would you say this?
Should I make it more complex?
For example, the first letter OF/FOR/IN the words for each month is big.
Thank you in advance. :)
