Morphology

dissection = dissect (transparent) = dissect + ion

Formed by the verb 'dissect' plus the nominalizing suffix '-ion'; the meaning 'the act of cutting apart' is directly derived from the verb.

Etymology

The word dissection comes from Latin parts dis- 'apart' and secare 'to cut', giving a simple image of 'cutting apart' to see inside. So a dissection is the act of cutting a body, organ, or other thing open to study its inner parts.
