Caput
A type of exotic option that consists of a call option on a put option. Essentially it gives the holder the right to purchase another option. This type of option is also known as a "compound option".
Investopedia Commentary
The holder of a caput option has the right to purchase a specific put option in the event that the price of the underlying asset declines. The disadvantage of a caput option is that it only trades over-the-counter, so it is not as easy to get into a position with caput options as with regular vanilla options.
