This meaning is much less common than intention.
Context and Usage

- Purposes
- Motives
- Future actions
- What someone means to do
Use intention only when discussing a technical subject where the term has its specialized meaning.
The Origin of Intention or Intension
Intention comes from the Latin word intentio, meaning “a stretching,” “purpose,” or “intent.” It entered English through Old French and developed into the modern meaning of a plan, purpose, or aim.
Intension has a related history. It also comes from Latin intensio, connected with the idea of stretching or extending. Over time, it developed a specialized meaning related to the qualities or content of a concept.
The spelling difference exists because the two words developed along different paths and gained different meanings.
Although they are related historically, intention became the normal English word for a person’s plan or purpose. Intension remained mainly a technical term.
British English vs American English Spelling
There is no major BritishifAmerican spelling difference between intention and intension.
Both American English and British English use:
- intention for a plan or purpose
