We can attach the kanji 方 (read as かた) to the verb stem to say “way of doing something” or “how to do something”—an especially handy phrase when you first set foot in Japan and there are many things you don’t yet know.
Critical Rule: Because adding 〜方 turns the verb phrase into a noun, the direct object particle を must change to the modifying particle の. For example, 漢字を読む (read kanji) becomes 漢字の読み方 (how to read kanji).
