There are so many words in English that are either so similar to each other in spelling and pronunciation or their meanings are so close to each other that it’s almost impossible to tell them apart. This is the case with inquiry vs. enquiry. These words are especially confusing because they suffer from everything mentioned above: they are spelled similarly, pronounced similarly, and their meanings are quite similar (if not the same).

Today, I want to clear up any confusion or uncertainty that you might have in using these words in your writing, so you will be absolutely sure which word to use and when.

Use of enquiry:

In American English, both words can be used interchangeably, with inquiry being the more common, preferred word. In British English, both words can also be used interchangeably, but it is preferred to used inquiry for formal investigations and enquiry for general questions. If you are a British English speaker/writer and are looking for a way to keep track of which word to use and when, just remember that inquiry is preferred when referring to an investigation.
