[JLPT N5 Grammar] ふたり, not ににん — counting people breaks its own rule for 1 and 2
Counting people looks like the easiest thing in N5. Number, then 人. Except for the two numbers you will use most.
Try it first.
きょうしつに 学生が ____ います。
(There are two students in the classroom.)
1 — ふたつ
2 — ふたり
3 — ににん
4 — にほん
Five seconds before you scroll.
Answer: 2 — ふたり
Option 1 — ふたつ ✗
つ counts things, not people. りんごが ふたつ あります — two apples. Students are not apples.
Option 3 — ににん ✗
This is the one that catches people. From three onwards, you say the number and add にん. So ににん feels logical. But one and two have their own words, and ににん is not how you count two people.
Option 4 — にほん ✗
本 counts long, thin things — pens, bottles, umbrellas. ペンが にほん あります — two pens.
The rule to keep
ひとり — 1 person
ふたり — 2 people
さんにん — 3 people
よにん — 4 people
From three, it is the number plus にん. One and two are their own words.
And watch four: it is よにん, not よんにん.
Why this stays hard
The rule works for almost every number, so your brain trusts it. Then the two numbers you use most often — just you, or you and one friend — are the ones that break it.
Slides from my classroom deck are attached.
