Q1. What do people first see in that word swell or swelt?
First, swelt isn't the past participle of swell; it's swelled, pronounced swell[d], not swel[t]. So, no, I didn't see 'swell' in Swelty.
Second, swelty is obsolete; people don't use it anymore. I had to look the word up in the dictionary--you can imagine my surprise when I read the 1st entery: to die, and that used for brand. Hmm.
Q2. Do you think the word "S W E L T Y" as a brand name would be cool for the US market (I'm French).
Uhm, yes and no. Yes, because it'd be a new word, so it could carry any meaning you market it to carry. No, because I don't know what the product is.Q3. Does it make you feel good, not good, does it have a funny name, is it ridiculous, is it too simple, is it too complicated, is it positive, negative?
What's the product?Q4. What is a good connotation for that word?
It's a new word for me, and I can't seem to connect it morphologically to any of the words I know. That I now know what it means ('cause I looked it up), I'd have to give to faint, swoon, etc.
