The most distant or remote point or position.
The furthermost point of the island is a beautiful spot for watching the sunset.
Furthermost → It is formed from "further" (from Old English "forð", meaning forward or onward) and "-most" (meaning the greatest degree or furthest). The word "furthermost" means the greatest distance or the most advanced position in a particular direction.
Think of 'forward' ('forð') and 'the greatest degree' ('-most') to remember that 'furthermost' refers to the farthest point or position.
