Reduplication (a natural language feature) which changes meaning, pluralize, emphasize etc. is basically doubling of the word, partially doubling it or doubling it with phonetic constraints.
Grice's maxim of manner, when one tries to be as clear, as brief, and as orderly as one can in what one says, and where one avoids obscurity and ambiguity.
The maxim of quantity, where one tries to be as informative as one possibly can, and gives as much information as is needed, and no more.
Does this doubling , oppose Grice's Maxim of Manner or Quantity?
Or if Grice's Maxims are not to be compared with one particular linguistic feature, does it follow all others?
