同義詞
  • binary

    broader; describes anything with two states, not necessarily logical (binary code, binary star)

  • logical

    much wider; about reasoning in general, not the specific true/false system

  • two-valued

    technical, mostly in mathematical logic textbooks

反義詞
  • fuzzy

    in logic, the opposite system: values can be anywhere between 0 and 1, not strictly true or false

文法句型

Boolean + noun (logic, value, expression, operator, search, algebra)

用法筆記

Almost always used directly before a noun (Boolean value, expression, operator, search, algebra, logic). Capitalised in formal writing because it comes from a person's name (George Boole), but lower-case 'boolean' is now standard in programming code (e.g. 'boolean isReady;' in Java).

常見錯誤

❌The answer was very Boolean.
✅The answer was a simple yes or no.
💡Boolean is not a degree word; it describes a type of value, not how strongly something is true.
❌a Boolean number between 0 and 9
✅a Boolean value, either 0 or 1
💡Boolean values have only two possibilities, not a range.
