GMAT Idiom: Many vs. Much

The difference between the proper use of the words "many" and "much" is the same as the difference between "less" and "fewer." One refers to things that can be counted; the other refers to things that can't.

Many

The word "many" is used to modify something that can be counted. For instance, there are many articles on this site. Many students will be taking the GMAT this week. Fans of the Kansas City Chiefs have many reasons to complain.

The same principle applies to to comparisons, which use the words "many more." For example: "Many more business schools accept the GMAT than the GRE." The rule is the same (items must be countable), except that it's a comparison when the word "more" is introduced.

Much

The word "much" is used when you're modifying something that can't be counted. You might say, "I don't have much aptitude for science," or "Ellen doesn't have as much talent as Franke does."

When considering whether something is countable, be very literal. You can't count "aptitudes" or "talents." You might be able to measure them in some way (perhaps test scores or external ratings), but unless you can literally count the word used, use "much."

A Subtle Distinction

Here's an example of the difference:

• With only one day left before his GMAT, Kevin didn't have much time left to study.
• With only one day left before his GMAT, Kevin didn't have many hours left to study.

The only difference is "time" and "hours." While time can be measured (in hours, minutes, etc.), you can't count "times." You can, however, count hours. Understanding this distinction is crucial to mastering the subtleties of GMAT grammar.
