To Install
To Equip, To Mount
transitive verb, ichidan verb
This is a combination of the words 据える, meaning "to install," and 付ける, meaning "to attach." Put them together and you're still going to install something or to equip something. There's just more hands on work happening.
The readings for this word are both kun'yomi readings. You learned them when you learned the kanji, so you should be able to read this on your own.
ここに戸棚を据え付けるつもりだよ。
I’m planning to install cupboards here.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
