What does the く in 無くしてく do?


In the song [深い森](https://www.youtube.com/watch?v=qIoDWTF0qSo) by Do As
Infinity, this comes up:

[code]

    僕たちは 生きるほどに
    失くしてく 少しずつ
    偽りや 嘘をまとい
    
[/code]

Is this 失くしてく a short-form of 失くしていく? Or is the く after the て-form of 失くす
something else?

Thanks a lot!




> Is this 失くしてく a short-form of 失くしていく?

Quick answer: Yes.

An English translation
[here](https://lyricstranslate.com/en/%E6%B7%B1%E3%81%84%E6%A3%AE-deep-
forest.html) also shows that it must be ていく because it shows the progression
of losing something

[code]

    As we go on living
    We lose something little by little
    Wrapped in deceit and lies
    
[/code]
