Usage

What is a basic definition of less?

Less refers to a comparatively smaller amount, quantity, or degree and can be used in this sense as an adverb, adjective, or noun. Less has several other senses as an adverb, adjective, noun, and a preposition.

Less is a comparative form of the word little, with the word least being the superlative. If something is described as less, it is “more little” than something else. Specifically, less by itself often means a smaller number or amount rather than physical size.

Less can be used in this sense as an adverb, adjective, or a noun. Because less is a comparative, it must be used to compare two or more things to make sense. For example, “This house is less” makes no sense by itself. You might wonder. “Less what?” When we include the item we are comparing the house to, you can understand what we mean: That house is really expensive, but this house costs less. 

  • Real-life examples: Used cars often cost less than new ones. You will earn less money in your first job than in your last job. You might start out with a lot of questions, but as you learn you may have less.
  • Used in a sentence: I really need to start eating less.
    We want to make sure nobody gets less food than anyone else.

    When it comes to using pink paint, less is more. 

The word less is often confused with the word fewer. For the most part, you can use the words less and fewer as synonyms when comparing amounts of things.

However, less can compare abstract, uncountable qualities, while fewer cannot. For example, one dog can be said to be less playful than another, but it cannot be said to be “fewer playful” than another.

What does -less mean? The suffix -less means “without.” It is also used occasionally to denote a failure or inability to perform. It is often used in a variety of everyday and technical terms.The suffix -less ultimately comes from Old English lēas, meaning “free from, without” or “false.”

Commonly Confused

Even though less has been used before plural nouns ( less words; less men ) since the time of King Alfred, many modern usage guides say that only fewer can be used in such contexts. Less, they say, should modify singular mass nouns ( less sugar; less money ) and singular abstract nouns ( less honesty; less love ). 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). With plural nouns specifying individuals or readily distinguishable units, the guides say that fewer is the only proper choice: fewer words; fewer men; no fewer than 31 of the 50 states. Modern standard English practice does not reflect this distinction. When followed by than, less occurs at least as often as fewer in modifying plural nouns that are not units or groups, and the use of less in this construction is increasing in all varieties of English: less than eight million people; no less than 31 of the 50 states. When not followed by than, fewer is more frequent only in formal written English, and in this construction also the use of less is increasing: This year we have had less crimes, less accidents, and less fires than in any of the last five years.
