Antagonyms, also known as auto-antonyms, contronyms, or Janus words, are words that have two opposing or contradictory meanings.

For example, the word "left" can mean either remaining or departed. If you say, "I left my keys," it means you departed without your keys. But if you say, "My keys are left on the table," it means your keys are remaining on the table.

Similarly, "clip" can mean to attach (as in clip a badge to your shirt) or to cut off (as in clip your hair).

"Bound" can mean heading towards a certain direction (as in bound for home) or restrained from movement (as in bound by chains).

So, antagonyms are words that can have opposite meanings depending on the context in which they are used.
