Pro Tip

Distinguish from 'discard'

'Jettison' often implies a deliberate action to reduce weight or improve safety, while 'discard' is more general. For example, 'jettison fuel' suggests an emergency, whereas 'discard old clothes' does not.

Gold Rule

Context matters

Use 'jettison' when the action involves reducing weight, improving safety, or abandoning a plan/idea. Avoid using it for everyday removal of items.

Word Origin

From Old French *jetison* (modern French *jetée*), derived from Latin *jectio(n-)* (throwing), from *jacere* (to throw). The verb form emerged in Middle English via Anglo-Norman French.

Usage Notes

Primarily used in technical, nautical, aviation, and business contexts. Avoid using in casual conversation unless mimicking a formal or technical tone.
