usage: Many usage guides say that fewer should be used before plural nouns specifying individuals or distinguishable units: fewer words; no fewer than 31 of the 50 states. less, the guides maintain, should modify only singular mass nouns (less sugar; less money) and singular abstract nouns (less doubt; less power). It should modify plural nouns only when they suggest combination into a unit, group, or aggregation: less than $50 (a sum of money); less than three miles (a unit of distance). Standard English practice does not consistently reflect these distinctions. The use of less or less than where usage guides recommend fewer (than) is common in most varieties of English: less than eight million people; no less than 31 of the 50 states; We did more work with less people. Though these uses are often criticized, they appear to be increasing in frequency.
an adjective-forming suffix meaning “without,” “not having” that specified by the noun base (careless; shameless); added to verbs, it is equivalent to “un-” plus the present participle of the verb, or “un-” plus the verb plus “-able” (quenchless; tireless).
