[Middle English resoun, from Old French raison, from Latin ratiō, ratiōn-, from ratus, past participle of rērī, to consider, think; see ar- in Indo-European roots.]

rea′son·er n.
Synonyms: reason, intuition, understanding, judgment
These nouns refer to the intellectual faculty by which humans seek or attain knowledge or truth. Reason is the power to think rationally and logically and to draw inferences: "Mere reason is insufficient to convince us of its [the Christian religion's] veracity" (David Hume).
Intuition is perception or comprehension, as of truths or facts, without the use of the rational process: I trust my intuitions when it comes to assessing someone's character. Understanding is the faculty by which one understands, often together with the resulting comprehension: "The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding" (Louis D. Brandeis).
Judgment is the ability to assess situations or circumstances and draw sound conclusions: "At twenty years of age, the will reigns; at thirty, the wit; and at forty, the judgment" (Benjamin Franklin). See Also Synonyms at cause, think.

usage: The construction reason is because is criticized in a number of usage guides: The reason for the long delays was because the costs far exceeded the original estimates. One objection is based on redundancy: the word because (literally, by cause) contains within it the meaning “reason.” A second objection is based on the claim that because can introduce only adverbial clauses and that reason is requires completion by a noun clause. Critics would substitute that for because in the offending construction: The reason for the long delays was that the costs. … Nevertheless, reason is because is still common in almost all levels of speech and occurs often in edited writing as well. A similar charge of redundancy is made against the reason why, which is also a well-established idiom: The reason why the bill failed to pass was the defection of three key senators. Both phrases are easy to avoid if desired.

The reason for something is the fact or situation which explains why it happens, exists, or is done.

I asked the reason for the decision.
The reason for this relationship is clear.

Be Careful!
Don't use any preposition except for after reason in sentences like these.

You can talk about a person's reason for doing something.

One of his reasons for coming to England was to make money.

You can also talk about the reason why something happens or is done.

There are several reasons why we can't do that.

However, if you are actually stating the reason, don't use 'why'. Instead you use a that-clause.

The reason that they liked the restaurant was its relaxed atmosphere.
The reason I'm calling you is that I know Larry talked with you earlier.

Note that the second clause in these sentences is also a that-clause. Instead of a that-clause, some speakers use a clause beginning with because.

The reason they are not like other boys is because they have been brought up differently.

This use of because is fairly common in spoken and informal English. However, some people think that it is incorrect, and you should avoid it in formal English.
