I am confused about using “mere” to show something is not large. Based on samples in the Cambridge dictionary:

  1. The plane crashed mere minutes after take-off.

So other samples:

  1. It cost a mere 20 dollars.
  2. The city receives a mere 20% of the parking revenues.

Based on the first example, I expect it to be rewritten as:

  1. It cost mere 20 dollars.

  2. The city receives mere 20% of the parking revenues.

Why in two other samples, it uses the article “a”, while “dollars” and “20%” are plural nouns?

The reason why the first example does not use an article while the two others do is because the first does not refer to a specific amount.

If instead of an unspecific number of minutes you were to say it crashed in ten minutes then you would instead write:

  • The plane crashed a mere ten minutes after take-off.

On the other hand, if we were to rephrase the other examples so that they do not refer to specific quantities then we could drop the "a":

  • It cost mere cents. (I changed dollars to cents, because though grammatically correct either way, cents sounds a lot better in this context).

  • The city receives mere percentage points of the parking revenues.

In a sense, you are wrong when you say dollars and 20% are plural nouns. In these usages, they are effectively being treated as if they were singular. The "mere" is not qualifying the items in the set individually as would be the case in the phrase "the boys are hungry", but the set as a whole. It is the 20 dollars as a collective unit that is mere. The case is not that each individual dollar is mere and there simply happens to be 20 of them.

To reveal this fact further, consider the grammatically correct phrase:

  • He quit his job after a mere 2 day period.


  • He quit his job after mere days.


  • He quit his job after a mere 2 days.

As you can see both the "a mere 2 day period" and "a mere 2 days" are treated the same way. This is because they are both referring to a 2 day chunk of time. A chunk of time that is taken as a whole and said to be meager.

    mere is starting to look weird now.. Jul 31, 2018 at 14:18
  • Sometimes "a mere..." should be used even when there's no specific amount mentioned (e.g. "a mere pittance.")

    @Daniel "a mere pittance" falls in the same category as "a mere dollar". A specific amount is mentioned and that amount is one. Yes, it might not look like it in the case of "pittance" since the word refers to an ambiguous amount of money but that doesn't change the fact that the number of pittances (the actual thing which is described as mere) is indeed one. The same is the case for "a mere pile of sugar". Indeed, we are not told how many grains of sugar make up the pile but that is irrelevant as it is the pile itself that is being qualified, not the sugar grains.

    @user2397282 If you aren't familiar with the term already, look up "semantic satiation." Jul 31, 2018 at 17:59

    Another piece of evidence that "20 dollars" as a value is singular: "20 dollars is a lot to pay."

Yes, it's a question of grammatical number.

The plane crashed mere minutes after take-off.

Minutes being plural, no explanation may be needed.


It cost a mere 20 dollars.

mere 20 dollars is a phrasal noun representing the "amount," hence singular. Cf. It cost an amount of 20 dollars.
