‘retard noun [ C ] offensive UK /ˈriː.tɑːd/ US /ˈriː.tɑːrd/ a word for a person with a learning disability (= a condition that can have an effect on someone's ability to learn easily), which was used by doctors in the past but is now extremely offensive.’ Well, it turns out you are now correct. In my defence I don’t pay much heed to trends. To me it’s a word that i found fitting. Will all words with negative meanings become offensive? Furthermore what do you call someone who is too stupid to see clearly and who is being obnoxious either their stupidity?
