What does retarded mean?

Answer 1

The verb to retard means to cause to move or happen more slowly. A fire retardant is something that may not make a thing completely fireproof, but will significantly slow the process of the thing becoming ignited. You can think of automobile breaks as retarding the motion of a moving vehicle.

The word was later associated with persons who were mentally or socially disabled in some way. At first the term was not meant or understood to be pejorative. It is no longer considered an appropriate label for any mentally physically or intellectively challenged persons.

It is currently and most often used as a derogatory term for a person who is considered slow, foolish, ignorant or mentally inept.
Though the word retard is used by some as a derogatory term to refer to someone of lesser intelligence than normal or in other derogatory ways, retard is a verb, not a noun. It means to cause to be slow; delay the development or progress, hinder or impede. In that sense, no one is actually a retard.
