-some forms adjectives meaning "producing X" or "having that quality": awesome, tiresome, troublesome, wholesome.
"handsome" does not come from "big hands": it originally comes from "handy" (skillful, useful). Today it means attractive (for a person) or considerable (for an amount of money: "a handsome sum").
Noun or verb + some. Produces adjectives.
"handsome" does not mean "having large hands" — the root "hand" here comes from "handy" (skilful, apt). In modern English handsome = attractive (of a person, especially a man) or considerable (of a sum of money).

In formal writing "awesome" = overwhelming, awe-inspiring: "the awesome force of the storm." In informal American speech "awesome" = great. Do not mix registers in formal writing.
"winsome" has no connection to "to win." It comes from Old English "wynn" (joy). "a winsome smile" = a charming and innocent smile.
"handsome" is unrelated to "hand" in the modern sense. "a handsome man" = an attractive man. "a handsome sum" = a considerable amount of money.
A trick to remember it
"-some" = produces that quality, as if the base word "infects" you with that feeling: tire-SOME = makes you tired. trouble-SOME = causes trouble. Trap: "handsome" does not come from literal "hand", it comes from "handy" (skillful), the meaning already shifted.
