Praise a chap not being in uniform (4)
I believe the answer is:
laud
'praise' is the definition.
(lauding is a kind of praising)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for laud that I've seen before include "Praise - celebrate" , "Give praise to" , "homage" , "Name of archbishop; praise" , "Praise acclaim" .)
