[UPDATED] This is a medical term derived from the Latin [incisus] or [incisura], meaning "to cut". The Greek word [Τομή] (tomí) from which the suffixes [-otome], or [-otomy] derive, have a similar meaning.
The root term is [-cis-] and uses of this term include:
• Incision : "To cut in" • Incisive: Something that "cuts in"
• Incisor: Refers to a type of tooth that has a "cutting in" action
• Excision: The prefix [ex-] means "out" or "outside". To cut out, or to extirpate. See the meaning of the suffix [-ectomy] here
• Circumcision: The prefix [circum-] means "around", or "in a circle". To cut around (in a circle)
