Research or Researches: Which is Correct? Simple English Explanations

Research or researches? Which one is correct?!

There seems to be a lot of misinformation about this on the web, as most people (including native English speakers) get this one wrong!

We can use research as a noun or verb.

By definition, research (verb form) means to investigate or search carefully. It is typically related to studious inquiries or examinations.

Research (noun form) means an investigation to establish facts and make conclusions.

Research or researches?

In a nutshell, we use research as a singular noun and researches as a plural noun but it is very rare to say the term researches. It is preferred to say “pieces of research,” “research studies” or “research projects” when talking about more than one.

Researches can also be used as a verb for the third person singular in the simple present tense.

Research (simple present tense): I research, you research, he researches, she researches, it researches, we research, you research, they research.

Research as a Noun

Research can be a countable and uncountable noun.

As a noun, research is usually used as uncountable. For example, we could say, the research is able to determine the demand for health drinks.

The plural countable noun researches is rarely used. It is used to distinguish between one or more sets of research.

For example, we could say “research conducted at Trinity College and University College Dublin” (we don’t know if this is a joint research project or a separate research project in both colleges).

Or we could say “researches conducted at Trinity College and University College Dublin” (separate research projects carried out at the colleges).

Is it correct to say researches?

As you can see from our examples, it is correct to say researches.

You must be warned, however, that while we can use researches as a plural countable noun, most English speakers have never heard this and might think this is incorrect.

Native English speakers prefer to say “some research,” “research studies” or “research projects” rather than “researches” nowadays. Researches as a term is seen as archaic and old-fashioned.

Can we say a research?

While research can be used as a countable and uncountable noun, it is never correct to say “a research.” However, we can say “a research student,” “much research” or “some research.”

It is much more common to use researches in the third person simple present (he/she/it).

For example, we could say, “he researches for his project in the library.”

Researches can also be used as a noun, as mentioned earlier.
