Tips
usage
Three spellings, one word: 啰唆 is the standard form, while 啰嗦 and 罗嗦 turn up just as often. It works as an adjective and as a verb: 别啰唆了, stop going on.
register
Mildly negative and thoroughly everyday, calling someone 啰唆 is an eye-roll, not an insult. Applied to a process rather than a person it drops the talking altogether and just means fiddly: 手续啰唆, too many steps.
