To redound, in this use, is to come back as praise: something you do other people’s opinion of you. It is a very formal, rather old verb. You almost never hear it in the street. Writers use it in set phrases, especially redound to someone’s credit or redound to someone’s honour — the good deed washes back onto their name. You can also say it redounds to the advantage of a group. You do not ‘redound someone’; the credit redounds to them. The old picture is of a wave flowing back, though nobody feels a wave when they use it now. In ordinary talk, people just say ‘that made him look good’.

組成From Latin redundō: red- ‘back’ + undō ‘to surge’, from unda ‘a wave’. The picture is a wave washing back.
