ambitious

The word "ambitious" originates from the Latin verb ambire, meaning "to go around" or "to solicit." This verb is composed of ambi- (around) and ire (to go). In ancient Roman political life, candidates would literally "go around" canvassing for votes and support. The associated noun ambitus thus came to signify this striving for favor, office, or honor. Over time, the sense evolved from the literal act of soliciting to the inner quality of eagerly desiring success, power, or achievement, which is captured by the adjective-forming suffix -ious.

Structure: ambit (go around, seek) + ious (adjective suffix) ambit: From Latin ambitus (a going around, circuit, striving for favor), from ambire (to go around, solicit). In this word, it functions as the core root conveying the sense of seeking or striving. ious: A common English adjectival suffix derived from Latin -iosus, meaning "full of" or "characterized by."
