Question

sort the words according to the meanings of their shared roots.
acyclic ocular oculist binoculars
prototype protolanguage monocular unicycle
first circle eye

Explanation:

• First: The root "proto - " means first. So, "prototype" (the first or original model) and "protolanguage" (the first language in a language family) belong here.
• Circle: The root "cycl - " means circle. So, "acyclic" (not circular in structure) and "unicycle" (a vehicle with one circular wheel) belong here.
• Eye: The root "ocul - " means eye. So, "ocular" (related to the eye), "oculist" (an eye doctor), "binoculars" (an instrument for seeing with two eyes), and "monocular" (for one eye) belong here.

Answer:

• First: prototype, protolanguage
• Circle: acyclic, unicycle
• Eye: ocular, oculist, binoculars, monocular
