Device vs. Devise – Which is Correct?

The key distinction between device and devise lies in their part of speech: device is a noun referring to a gadget or plan, while devise is a verb meaning to invent, plan, or contrive. Both words are correct, but they are never interchangeable.

Device or Devise – Which is Correct?

Both “device” and “devise” are correct words in American English, but they serve entirely different grammatical functions and have distinct meanings. The confusion often arises because they are homophones (or near-homophones) and share a similar root, yet one is a noun and the other is a verb.

Device (pronounced dee-VICE) is a noun. It refers to an item of equipment or a mechanism designed for a particular purpose, or a plan/scheme. Think of it as a tangible thing or a specific strategy.

Devise (pronounced dee-VIZE) is a verb. It means to plan or invent (a complex procedure, system, or mechanism) by careful thought. It describes the action of creating or planning.

The Best Trick to Remember the Difference

The simplest trick to remember the difference is to associate the “c” in device with “contraption” or “creation” (both nouns), and the “s” in devise with “strategy” or “scheme” (when used as a verb, to strategize or scheme). Alternatively, remember that “advise” (a verb) ends with an “se,” just like “devise” (a verb). The “s” sound at the end of “devise” often signals a verb, similar to “surprise” or “rise.”
