再入力 what kanji is this?
 

I saw it but i have no clue, i have only been learning japanese in my high school so far

"Enter Again"

thank you very much

Nagoyankee can you explain it or at least the reading of it? Sainyuu means re-enter but what has the third kanji to do with it? And which reading you use? (ryoku, riki or rii...hee hee long time to study a bunch of kanji readings by heart and when I face them I don't know which reading to pick)

Not Nagoyankee, but I`ll help.

入力 is used for the entry of fields - usually text fields. Online, it`s used for "text entry", or "fill in".
It`s not split into 再入 and 力, but rather 再 is applied to 入力. So it`s basically "re-enter text".

In this case, 入力 is one word read as nyuuryoku.

再入力　＝　さいにゅうりょく

再（さい）　＝　again

入力（にゅうりょく）　＝　entering or inputting information

Do NOT think of this term as 再入 + 力. Think of it as 再 + 入力.

You need to learn this kanji 再 as you will see it again and again.

EDIT： Nyororin beat me to it.

The "enter" here is to do with inputting so 入力 "nyuuryoku" is used.

Oh geez, I'm so slow..

Thank you everyone, I appreciate the (multiple hee hee) explanation.

That made me laugh.
