What's the difference between these three words:intent, intend and intention
I know that all of them have the meaning of "planning to do something" or "determining to do something".
But I am very confused about the difference between these three words. And I want to know the situation to use these three words respectively.
If you can give some examples, it couldn't be better^^
Thank u

Answer

Intend is a verb; intent and intention are nouns.  Intent and intention are the same (in most situations).  Examples:

2.  My intent/intention (noun) is (verb) to go to college next year.   My intent (noun) is (verb) to quit my job next month.  My intent/intention (noun) is (verb) to prove that I am a better basketball player than he is.

3.  He had good intentions (noun, meaning what he hoped to accomplish), but things turned out badly.

she denies possessing the drug with intent to supply.
he was charged with wounding with intent
