Root Breakdown

Root-derived
jett-throw, cast
+
-isonsuffix
=jettison

From Old French jetteson (a throwing overboard), from jeter (to throw), from Latin jactare (to throw repeatedly, a frequentative of jacere). The -ison suffix comes from Latin -itionem (act of). Jettison preserves the most ancient, literal meaning of the entire ject family: physically throwing things.

Why It Means This

Jettison is the ject family's most literal survivor. In maritime law, jettison means throwing cargo overboard to save a sinking ship — a desperate, calculated sacrifice. The word entered everyday English as a vivid metaphor: jettison a bad habit, jettison an unprofitable division, jettison your plans. The physical drama of cargo splashing into the sea gives the figurative use its emotional weight — you don't casually jettison something; you throw it away because you have to.
