Why is it a word to the wise?

Question

the wise don't need to know anything, it should be a word to the stupid.

Answer 1

It's a slight corruption. It's really "A word to those who would be wise."

The wise don't know everything. However, they do know that they should heed warnings.

The stupid do not heed warnings, despite their level of knowledge.

Answer 2

Verbum sapienti sat,” the Latins had it: a word to the wise suffices; Literally “a word is enough for a wise man.”

Sat sat dictum sapienti, “a word to the wise” is a commonplace in classical authors.

"A word to the wise" was a very popular play in the 1770's and likely expanded the use of this phrase around since the 1500's.

"A word to the wise is enough, and many words
won't fill a bushel."— Poor Richard Improved, 1758

Answer 3

I have something to tell you and it takes only a word to a wise person to get across what I have to say (not a long story.)
A word to the wise should be sufficient.

Answer 4

Because fools don't listen to wise words. They resent those who try to give them wise advice and instruction. Read the books of Proverbs and Ecclesiastes, the one who wrote them is wise.

Answer 5

its no use telling the fools because they will not heed the words so a word to the wise hoping they will heed the advice
