Refers to one's inner state, what one has in mind, or one's intention. Often used in compounds and set phrases.
Used for the meaning or significance of words, actions, or symbols. Common in compounds like 意味 (meaning).
He expressed his gratitude.
Understanding his intention, I left the place.
It is important to respect the other person's feelings.
Please explain the meaning of this word.

意向 refers to a concrete intention or plan one holds, whereas 意 is the vaguer, more literary notion of one's inner thoughts or feelings.
意志 stresses firm will or determination, while 意 is a broader, softer term covering any thought or feeling one has in mind.
意図 specifically means a purpose or aim behind an action, whereas 意 more generally covers one's feelings or thoughts without implying a plan.
異 (also read い) means 'different' or 'other', unlike 意, which means 'thought' or 'meaning'; the two are easily mixed up in compounds because they share the same sound.
