What does聽trifurcate mean?

Trifurcate means to divide or fork into three branches.

Things can trifurcate on their own or in an otherwise passive way, as in That鈥檚 where the river trifurcates into three branches, or they can be trifurcated by someone, as in We trifurcated the road into three lanes so more people could exit at once.聽

The word trifurcate can be used as an adjective meaning divided into three branches, but the adjective trifurcated is more commonly used in this way. The word trifurcation refers to the act of trifurcating or something that is trifurcated. These terms are most often used in technical and scientific contexts, such as engineering and medicine.

The related and more common word bifurcate means to divide or fork into two branches.

Example: The hiking trail trifurcates after about four miles, so make sure you go down the middle path and not the ones on the right or left.

Where does聽trifurcate come from?

The first records of trifurcate come from the mid-1600s. It comes from the Latin trifurcus, from the prefix tri-, meaning 鈥渢hree,鈥 and furc(a), meaning 鈥渇ork鈥 (as in a fork in the road or a river).

When a road or a river splits into two, you鈥檇 say it forks, or even bifurcates. Saying it forks can indicate that it splits into multiple channels, but if you want to specifically say that it splits into three, you can say it trifurcates. Trifurcate is used in many contexts in which structures are discussed in technical or scientific terms. Trifurcations can be found throughout nature, including parts of the human body that fork into three different channels, such as some arteries of the heart.
