• GRADER phrases such as "not", "somewhat", "rather", "fairly", "quite", "[clearly] [so] very", and "[almost entirely] too", which are used to modify vague quantifiers like "few", "little", "many", and "much" and gradable adjectives like "big" and "green"..
• DOWNTONER phrases [Quirk 8.111] like "hardly", "[just] barely", "scarcely", and "just"
• Comparative GRADER phrases which include GRADER phrases, DOWNTONER phrases, and words like "far" and "way", which can modify the comparative quantifiers "fewer", "less", and "more", and prepositions like "over", "under", "near" and "beyond".
• Superlative graders like "[almost] entirely" and "completely" which can be used in phrases like "[almost] entirely too many", "entirely behind the house" and "completely green".
• LIMITERs like "just", "only",  "merely", and "not even".
• EMPHASIZERs like "even", "really", and "not only".
• THRESHOLDERs like "enough" and "sufficiently", which are used in phrases like "[almost] enough more food", "few enough people", and "sufficiently many others".
• INTERROGATIVEs "how" and "however" ("how[ever] many guests were there?", "how blue is the sky?"), which can also be used as exclamatories or uncertainties ("how beautiful a flower!", "however much money he has is not enough").
• ATTITUDE phrases like "[just] possibly", "[very] clearly", "[rather] probably", and "hardly" which are used in phrases like "just possibly my best work", "hardly a hundred dollars", or "probably more than enough tickets".

Some words and phrases fall into more than one of these syntactic categories because their use can be ambiguous.  For example,  "hardly a hundred dollars" in a sentence like "Hardly a hundred dollars will be sufficient" can have a meaning like "A hundred dollars will hardly be sufficient" (that is, "hardly" applies semantically to the entire noun phrase) or like "A hundred dollars or a bit less will be sufficient" (that is, "hardly" applies semantically to "a hundred").  Similarly, "just" in "just the best wine" has an attitudinal meaning synonymous with "simply" or "quite" in "It's just the best wine I've ever tasted", but it can also have a limiting meaning synonymous with "only", as in "Bring just the best wine you've got", which can imply "Your best wine may not be very good, but bring it anyway."

This module will probably require reorganization when semantic computations are added to it.
