It's a combination of two words:
* Magka-: This prefix indicates "mutual" or "each other".
* Salungat: This word means "opposite" or "contrary".
Therefore, "magkasalungat" literally means "opposite to each other". It can be used to describe things, ideas, or people that are completely different or in conflict with each other.
Examples:
* Magkasalungat ang kanilang mga pananaw. (Their views are opposite.)
* Ang init at lamig ay magkasalungat na konsepto. (Heat and cold are opposite concepts.)
* Magkasalungat ang kanilang mga layunin. (Their goals are contradictory.)
