Surface Forms

abscission singular
abscissions plural

Morphology

abscission = scission (transparent) = ab + scission

Formed by the prefix 'ab-' (away) added to 'scission' (cutting), giving the clear meaning 'cutting away' or separation.

Etymology

Abscission comes from the Latin parts ab- meaning 'away' and scindere meaning 'to cut'. Think of it like using scissors to cut something away, so abscission means the act of cutting off or separating a part, as in surgery.
