Meaning of GOOD in English
Date: 13th century
1 : WELL <he showed me how good I was doing ― Herbert Gold>
2 ― used as an intensive <a good 200 pounds> <a good longitude time>
usage Adverbial good has been under attack from the schoolroom since the 19th century. Insistence on well rather than good has resulted in a split in connotation: well is standard, neutral, and colorless, while good is emotionally charged and emphatic. This makes good the adverb of choice in sports < “ I'm seeing the ball real good ” is what you hear ― Roger Angell>. In such contexts as <listen up. And listen good ― Alex Karras> <lets fly with his tomatoes before they can flee. He gets Clarence good ― Charles Dickinson> good cannot be adequately replaced by well. Adverbial good is primarily a spoken form; in writing it occurs in reported and fictional speech and in generally familiar or informal contexts.
