A suitcase word is a word that carries many meanings or invites multiple interpretations, so that what it means depends heavily on context. "Intelligent" is a classic example: calling a person intelligent and calling a dog intelligent describe very different things, even though the same word is used.
Why it matters: Language is ambiguous by nature, and suitcase words make that worse. In talks, documentation, requirements and bug reports, they let each reader unpack their own meaning, which leads to misunderstandings that surface late. For testers, spotting suitcase words is a quick way to find hidden assumptions and gaps in shared understanding.
In practice: Avoid suitcase words where precision matters, or give enough context to pin down the intended meaning. When writing or presenting, replace a vague word with what it actually refers to. When reviewing requirements or user stories, treat words like "fast", "secure", "simple", "intelligent" or "user-friendly" as prompts for questions: fast for whom, measured how, compared with what? Writing the agreed meaning down stops it drifting later.
Examples:
- A story asks for an "intuitive" sign-up flow, and the tester asks the team to describe what a new user should be able to do without help.
- A conference slide promises "smart" test automation, and the speaker adds a sentence explaining that the tests pick data based on recent production failures.
- A bug report says a page is "slow", and the reporter adds the measured load time and network conditions.
Common pitfalls:
- Assuming everyone in the room shares the same meaning for a familiar word, so nobody thinks to check.
- Replacing one suitcase word with another, such as swapping "robust" for "resilient", without adding any real detail.
Why do suitcase words matter for accessibility? Clear, precise language helps everyone, including people reading in a second language, people using captions or transcripts and neurodivergent readers who may take words literally. Unpacking suitcase words makes content easier to follow for the whole audience.
