Monthly payment in English is "monthly fee" or "monthly payment plan". This term is commonly used when discussing financial arrangements or subscriptions where the payment is made on a regular monthly basis.
I was in this tiny little café in Paris, you know, the kind where they serve croissants that could almost melt in your mouth, and I remember the first time I asked for a "monthly payment" in English. It was like a simple sentence, but it felt like a big deal. "Monthly payment, please," I said to the barista, who was this young French guy with a sketchbook. He nodded, not missing a beat, and gave me a receipt for 25 euros, which was the monthly fee for my Wi-Fi. Time, 10:45 AM, on a sunny Thursday in May. I guess sometimes, it's the little things that connect us across languages and cultures. Wait, there's this other thing... I suddenly think about the first time I learned "monthly payment" in English, it was during my college years.
