Collocations

Mnemonic

还 huán "to return" + 原 yuán "original": to return to the original, i.e. to restore, to reduce (in chemistry). It corresponds to the Korean word hwan-won (還元). Three shades: restoring a state (还原设置 to restore settings), revealing the truth as it was (还原真相), and chemical reduction (氧化还原 redox). 还 is a polyphone: huán "to return" (归还) but hái "still, also" (还是); here it is huán.
