Intention or Intension: Which Is Correct?

Updated 2026-10-12 · Which One Is Correct editorial team

Quick answer: The word intention is the standard choice for describing a personal plan or aim, while intension is a specific term in logic and philosophy. Most people confuse these two because they sound identical, but their meanings and uses are distinct. Knowing which one to apply depends entirely on whether you are discussing a future goal or the inner definition of an idea.

The Short Answer

An intention is a plan or aim that you intend to carry out, whereas intension is a technical term in logic and philosophy for the inner meaning of a concept.

People often mix these words up because they share the same pronunciation and the first few letters look nearly identical. This confusion happens even more often because intension was once an older word for intensity, adding another layer of difficulty for those who encounter it in older texts.
