And another question, a lesson or lessons

[Yoshio]

Hello again, there's another question.

Is the below sentence OK?

"I have a piano lesson every Monday."

Usually piano students take lessons continuously.
If so, should I use the plural form of "lessons"?
Considering the word "every" is used in the sentence, I think I should use singular rather than plural form unless the person takes more than one lessons on Monday.

Am I right?

Thank you for your help

Hi, Yoshio,
I think there's no difference at all.

Thank you very much for your reply.

We Japanese don't use plural form very often, though we have some.
Usually we just put numbers or words like "many" before a noun and don't change the form of the noun into plural form.

I always think there should be something difficult about the use of singular or plural form but things usually turn out to be easier than I think

Anyway, thank you for you help. I really appreciate it.
