週に2回、日本語を勉強します。
I study Japanese twice a week.
A frequency.
Daily Japanese
How often?｜週に2回・月に1回
Describe frequency by putting a period before に and a number before 回. Keep the number of times separate from how long each activity lasts.
『週に2回』は、1週間の中で2回するという意味です。1回に何時間するかは、この言い方だけではわかりません。
Build the pattern
Use period + に + number + 回: 週に2回. 回 follows the number and counts occasions.
『週に』『月に』『年に』の後ろに、回数を言います。
Change the period carefully
週に1回 is once a week. 月に1回 is once a month. The same number has a different meaning when the period changes.
『週』と『月』をよく見ましょう。『1回』が同じでも、頻度は違います。
Add an approximate amount
Add ぐらい after 回 when the frequency is approximate: 月に2回ぐらい. に may be omitted in some expressions, but practise the full form first.
だいたいの回数は、『月に2回ぐらい』と言えます。
Do not turn times into hours
週に2回 describes two occasions each week. 1回2時間 describes a length of two hours per occasion. One expression does not automatically tell you the other.
『2回』と『2時間』は違います。回数と時間を分けて聞きましょう。
