“More” can refer to a greater amount, a larger number, a higher level or stronger intensity. Its opposite changes with the noun and comparison, so less and fewer are only the starting point.

Less
Less is the standard opposite for smaller amounts of uncountable nouns and lower degrees.
Example: The revised process uses less energy.
Fewer
Fewer is the standard opposite for a smaller number of countable items or people.
Example: Fewer applications arrived this month.
Lower
Lower contrasts with more when comparing levels, rates, prices or measurements.
Example: The second group had lower average costs.
Smaller
Smaller is appropriate when more implies greater size, scale or quantity.
Example: A smaller sample was used in the pilot.
Reduced
Reduced describes an amount, level or quantity that has been deliberately or measurably made lower.
Example: The service is operating at reduced capacity.
Decreased
Decreased describes something that has become lower in quantity, rate or intensity.
Example: Demand decreased during the winter.
Diminished
Diminished suggests a reduction in strength, importance, amount or effect.
Example: The medication had a diminished effect over time.
Lesser
Lesser is a formal comparative meaning smaller in degree, importance or rank.
Example: The court considered the lesser of the two penalties.
Limited
Limited emphasizes that only a restricted amount or range is available.
Example: Only limited funding remains.
Scarcer
Scarcer means less readily available or present in smaller supply.
Example: Affordable housing became scarcer.
Shorter
Shorter contrasts with more when the comparison is duration, length or extent.
Example: The revised meeting was much shorter.
Weaker
Weaker contrasts with more when more implies greater strength, force or intensity.
Example: The signal became weaker farther from the transmitter.
Use Less and Fewer Correctly
Use fewer for countable items such as people or errors and less for uncountable amounts such as time or water. Lower, smaller, shorter and weaker are better when the comparison is specifically level, size, duration or strength.
The grammatical distinction between less and fewer is especially useful in edited prose, but real-world usage varies in some fixed expressions. If the sentence sounds awkward, recast it rather than forcing a comparative simply to avoid more.
