Kanji Kuma1. The doing pattern
Subject は Object を Verb
Reverse everything after the subject
English: Jack orders a hamburger. Subject, verb, object.
Japanese keeps the subject first, then reverses the rest: Jack, a hamburger, orders. Subject, object, verb. The verb always comes last. Wait for it.
Two sounds glue the parts together. は (said "wa") comes right after the subject. を (said "o") comes right after the object.
ロバートさんはハンバーガーを注文します。
Robert orders a hamburger.
私はコーヒーを注文します。
I order coffee.
The します converter
Japanese has a converter that turns foreign words into verbs: put します after the word. Japanese people already know order, cancel, email, copy, delete from six years of English class, so 注文します (order + します) is a real verb everyone says at McDonald's.
On the cards, a verb of this kind is two pieces: the word, then します. That is the whole doing pattern. With it you can already say dozens of things.
私はスケジュールをメールします。
I email the schedule.
私は予約をキャンセルします。
I cancel the reservation.
私はファイルを削除します。
I delete the file.
Drop what is obvious
If it is clear you are talking about yourself, drop 私は. At a counter, これを注文します ("I'll order this") is complete and natural. Japanese leaves out anything the listener can guess.
これを注文します。
(I) order this.
