In Japanese, there’s a verb form that ends with て or で. You use the て form with ください to give requests!
If a verb has an e sound before ‑ます, remove ‑ます and add ‑て.
If a verb ends in ‑みます or ‑びます, remove the ending and add ‑んで.
There are a few other patterns and exceptions, as well. For example, します becomes して.
