八歳(はっさい)といえば、日本(にほん)では小学校(しょうがっこう)二年生(にねんせい)にあたる年齢(ねんれい)だ。
Eight years old is the age of a second grader in elementary school in Japan.

Composed of (はち/はっ) (eight) and the age counter (さい) (also written (さい)). The number (はち) undergoes promotion to はっ before さい, producing the sokuon (small つ) pronunciation はっさい rather than はちさい.

USAGE:
Routine vocabulary for stating ages. The counter (さい) is used for human and animal ages; in casual writing and on children's products, the simpler (さい) is often substituted. Ages are typically asked with 何歳(なんさい)ですか (How old are you?) or the politer おいくつですか. With the copula, one says 八歳(はっさい)だ・です.
