ЧИСТИТЬ _|_ TO CLEAN / CHISTIT [ˈt͡ɕisʲtʲɪtʲ]
Hint with an alternative definition: to search for dirt and then put it to a ditch (cleanout) while chore, like to bring back «shining chastity» by removing the dirt or to switch from a «dirt» to «clean» state.

Hints with translation + consonant words (by sounds or letters): to clean dirt like Christ cleans sins (Christ > chist)
