Device and devise look almost identical, but they have different meanings and grammatical functions. A device is usually a noun meaning a tool, instrument, or technique. Devise is usually a verb meaning to invent, develop, or carefully plan something.

The words also sound slightly different. Device ends with an S sound, while devise ends with a Z sound.
Although the basic distinction is straightforward, there are other important uses to understand. A device can be a literary technique rather than a physical object, and devise has a specialized meaning in legal English.
