Form
Tense
suffix
The kanji and the word share one of the same meanings: form. It doesn't just mean form though, it means tense too. Like verb tense.
This has the same reading as the kanji you learned, meaning you know the reading!
ます形
masu form
です形
desu form
て形
te form
「出る」の「て形」は「出て」です。

「大切な人だった」？どうして今、カコ形で言ったの？
"You were an important person?" Why did you say it in the past tense?
