Less Then vs. Less Than – Which is Correct?
The correct phrase is less than. The phrase “less then” is a common grammatical error resulting from the phonetic similarity between “than” and “then.” Always use “than” when making a comparison, and “then” when referring to a sequence of events or time.
Less Then or Less Than – Which is Correct?
The correct comparative phrase is less than. The phrase “less then” is always incorrect. This common mistake stems from the phonetic similarity between the two words, leading many to confuse “than,” which is used for comparison, with “then,” which indicates time or sequence.
The Best Trick to Remember the Difference
The easiest trick to remember the difference is to associate “than” with comparison, just like you would with “more than” or “greater than.” If you are comparing two things, you need “than.” If you are talking about a sequence of events or a point in time, you need “then.”
Swap Test: Try substituting “more than” into your sentence. If it still makes sense, you likely need “than.” If you’re discussing “first, then second,” you need “then.”
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| Less Than | Comparative Phrase | A smaller quantity or degree compared to something else. | He has less than five dollars in his wallet. |
| Less Then | Incorrect | Grammatically incorrect; a misspelling of “less than.” | (Incorrect usage: “It was less then I expected.”) |
How to Use Less Than
“Less than” is a comparative phrase used to indicate a smaller amount, quantity, or degree when compared to another. It is typically used with uncountable nouns (e.g., water, time, money, information) or singular nouns that represent a collective amount. While traditional grammar dictates “fewer than” for countable nouns, modern usage often sees “less than” applied more broadly, even with countable items, especially in informal contexts or when referring to a single quantity (e.g., “less than 10 items”). However, for formal writing, it’s best to stick to “fewer than” for individual countable items.
For those seeking a more comprehensive understanding of this specific grammatical choice, a deeper look into Fewer vs. Less is recommended.
Example 1: The project will require less than two weeks to complete, assuming no delays.
Example 2: She felt less than thrilled about the unexpected change in plans.
Example 3: You should use less than a teaspoon of salt for this recipe.
Etymology of the word Less Than
The word “less” originates from Old English læs, meaning “smaller, fewer, not so much,” which itself comes from the Proto-Germanic *laisiz. It has been used as a comparative form of “little” for centuries. “Than” comes from the Old English þanne, þænne, a variant of “then,” used to introduce the second element in a comparison. The combination “less than” has been a standard comparative construction in English for a very long time, consistently indicating a deficit or inferiority in quantity or degree.
