Here is something that has been bothering me for a while now: How to know how the letter changes inside words like for example 一杯、二杯?
More concretely, I really need to know how to correctly count strides. I've heard people say it but I can't make sense of it so I keep forgetting and end up being too embarrassed to make sentences that involve counting strides (of a cantering horse).
I know one is 一歩{いっぽ} and perhaps 二歩{にほ} but after that I have no clue whatsoever whether it changes to b, p or stays h.
Please could someone teach me the correct way to count strides from 1 to 10?
And, well, it would really help me if you could explain the system to me so that I can reuse it for cups of coffee and whatever else I may be counting in the future and don't have to ask it again here. > . <
