I recently discovered that in the Missouri legal dialect, arguments supporting or opposing motions are referred to as “suggestions.” For example:
A party filing any motion, except motions for new trial, motions for trial settings, or motions which require proof by introduction of evidence (as distinguished from proof by affidavit pursuant to Supreme Court Rules), shall serve and file at the same time brief written suggestions in support thereof, together with authorities relied upon.
While the use of “suggestions” is not exclusive to Missouri, the state is certainly a key player in popularizing this terminology.
