the.com/boon

means A timely benefit or gift — something that helps you out, often freely given rather than earned.

from From Old Norse 'bón,' meaning a petition or request granted, which traveled into Middle English carrying that sense of 'a favor asked for and received.' Over time the word drifted from the asking to the getting — a boon stopped being the request and became the good thing granted, which is why it still carries a faint echo of favor owed, of someone having petitioned the universe and been answered.
