Sever vs. Severe – Which is Correct?

The words sever and severe are distinct in both meaning and grammatical function. Sever is a verb meaning to cut off or separate, while severe is an adjective describing something very intense, strict, or serious. Understanding their different roles in a sentence is key to using them correctly.

Sever or Severe – Which is Correct?

Both “sever” and “severe” are correct words in American English, but they belong to different parts of speech and have entirely different meanings. The confusion often arises due to their similar pronunciation and spelling.

• Sever (verb): To cut off, separate, or break off.
• Severe (adjective): Very great; intense; harsh; strict; serious.

You cannot interchange these words, as doing so would drastically change the meaning of a sentence or render it nonsensical.

The Best Trick to Remember the Difference

A simple trick to remember the difference is to associate each word with a related concept:

• Think of sever as an action, like a serrated knife that cuts. The ‘v’ in ‘sever’ can remind you of a cutting action.
• Think of severe as a description, often associated with something serious or very intense. The double ‘e’ can remind you of the intensity or extent of something.

Another trick is the “Part of Speech Swap Test.” If you can replace the word with another verb (like “cut” or “detach”), you likely need “sever.” If you can replace it with another adjective (like “harsh” or “intense”), you need “severe.”

Word	Part of Speech	Meaning	Example
Sever	Verb	To cut off, break off, or separate (e.g., a limb, a connection).	The surgeon had to sever the damaged nerve.
Severe	Adjective	Very great, intense, harsh, strict, or serious.	We are expecting a severe thunderstorm tonight.
