:"Items in a series may be separated by commas:
:Complacency, urbanity, sentimentality, whimsicality
:They may also be linked by coordinating conjunctions such as ''and'' or ''or:''
:economists, sociologists or political scientists
:the good, the bad and the ugly
:Opinions differ on whether and when a comma should be inserted before the final ''and'' or ''or'' in a sequence. In keeping with the general trend toward less punctuation, the final comma is best omitted where clarity permits, unless there is a need to emphasize the last element in a series."
