三十人(さんじゅうにん)

さんじゅうにん
noun
thirty people
quantity
1. thirty people
Thirty persons, formed with the counter 人(にん). From 四人(よにん) upward the counter is regularly にん, so no sound change occurs here.
クラスは三十人(さんじゅうにん)だ。
The class has thirty students.
約(やく)三十人(さんじゅうにん)が会議(かいぎ)に参加(さんか)した。
About thirty people took part in the meeting.
Capacity is thirty people, so if there are many applications there will be a lottery.

三十(さんじゅう) (thirty) + the counter 人(にん). Only 一人(ひとり) and 二人(ふたり) are irregular, and 四人(よにん) shortens よん to よ; otherwise the count simply adds にん.
