Morphology

bisection = sect (transparent) = bi + sect + ion

The prefix 'bi-' is transparently added to 'sect' to form 'bisect', meaning to divide into two parts.

Etymology

The word bisection comes from the parts bi- meaning 'two' and sect meaning 'to cut', as you see in bicycle ('two' wheels) and section ('a cut' or part). So a bisection is the action of cutting or dividing something into two equal parts.
