About This Root

From Latin jacere (to throw), past participle jectum. One of the most versatile roots: prefixes control the throwing direction — inject (throw in), project (throw forward), reject (throw back), eject (throw out), object (throw against), subject (throw under). Each prefix creates a distinct, common English word.
