The English language can sometimes drive me crazy-er. If I had to learn it as an adult, I would be mute forever....hhmmm, interesting theory. Even so, there are situations where I just cannot come up with the correct word, pronunciation, or grammar.
Definition of Well-In a Good or satisfactory manner.
Definition of Good-Satisfactory or high quality.
So, when one is sick, we say "Get well soon". After all, saying "Get Good Soon" would just be silly.
How about "How are you feeling today?"
"I feel good"
"I feel well"
"I am well"
"I am good"
Then the person that asked the question would respond "Good".
So I suppose that new dress looks good because I wear it well. But if I ask you how it looks and you say "good" then I will be pleased but it I ask you and you say "Well" then I will be standing there waiting for you to finish your sentence with something like, "Well, I've seen better" which would be better than saying "I've seen gooder".
Quite often we will say "Good Luck" but I haven't heard anyone ever say "Well Luck".
Also, if Well is Good then why do we use it to start a response that usually is not good....ie the response about the dress "Well, I've seen better". Isn't that like saying "Good, I've seen better"? But it could also mean "UGH, I've seen better".
Well is a wonderful segway into any new conversation but Good would be odd.
On the phone, Well usually means "I'm getting ready to end this call". Which can sometimes be Good because you may have been on the phone too long and your head is starting to hurt in which case you aren't feeling Well at all.
Not to mention that it would be hard to fetch a pail of water out of a Good. But quite easy to fetch a pail of water out of a well.......except does anyone really ever use the word fetch other than when talking to their dog?
Well, that's another thought for another day.
Have a Good Day!
