A forked tongue is a tongue split into two distinct ends at tip. This is a feature common in many species of reptiles. The reptiles smell using the tip of their tongue, and a forked tongue allows them to tell from which direction a smell is coming from.
It has given rise to the expression "to speak with a forked tongue," meaning: To say one thing and mean another and in more general terms, to act in a duplicitous manner.
