Is 'brittle' the same for a cracked material as it is for a person? The meanings are linked, but not the same. A brittle material tends to break instead of bending. Calling a person "brittle" suggests that the person is tense or easy to upset. The first can be a useful technical term. The second is a broad personal judgment.

Learn "Brittle" in depth →What's in scope, and what isn't
The physical meaning of "brittle" is the source of the work metaphor. It matters in technical fields such as design, safety, and engineering. In those fields, people may need to use and test the term with care. The personal sense of "brittle" is different. It can sound unfair because it labels a person instead of naming observed conduct.
"The old plastic casing is brittle and cracks if you squeeze it" uses the literal meaning. It shows how the physical property can lead to a metaphor about a weak response to stress.
"Alex seems brittle in meetings" uses the personal sense. It is a vague and risky judgment, so describe the conduct you observed instead.
The word also appears in food, health, hair care, earth science, and biology. Examples include "peanut brittle," "brittle bones," and "brittle hair." Those uses are outside this workplace guide, but they are valid uses of the word.

The common mistake: treating either boundary sense as a production target
The mistake is to treat both senses as if they make the same kind of claim. A test may support a finding that a material is brittle. A personal label rests on an interpretation of someone's conduct. For people, describe the act, setting, and effect instead of making a broad judgment.
Learn both senses so you can read "brittle" in context. Use the literal term when the material facts support it. At work, the metaphor often describes systems, processes, or plans that may fail after a small change. That claim also needs facts about the system and the kind of stress involved.
Practice scenarios
Practice using brittle in cases like:
- describing a material when a test supports the physical meaning
- noticing when a personal label hides the actual conduct at issue
- describing how a system may fail under a stated kind of stress
Useful practice phrases:
- "The casing is brittle and may crack under light pressure."
- "In the meeting, Alex raised their voice after two questions."
- "Here, brittle describes a material, not a person's conduct."

Use the physical sense for supported material facts. For people, describe conduct instead of using a broad label.
