Calmly Consider Whether to Use “Unemotional” or “Phlegmatic”

Quick summary

Unemotional can suggest coldness or detachment, while phlegmatic often implies steadiness and self-control.

Unemotional and phlegmatic both describe a certain lack of reaction, but one has a neutral or slightly negative tone, while the other can be an admirable quality in some situations. Here’s how to know which one to use: 

Unemotional

Unemotional describes someone who doesn’t show strong feelings — or any feelings at all.

Phlegmatic

Phlegmatic refers to someone calm, composed, and not easily excited or upset.
