Question: is phalanx singular or plural?
Answer: Phalanx: Anatomically, any one of the bones in the fingers or toes. (Plural: phalanges.) There are 3 phalanges (the proximal, middle, and distal phalanx) in most of the fingers and toes. However, the thumb and large toe have only two phalanges that accounts for their being shorter.
