Question

1. explain the relationship of the entry word trajectory to its latin word origin.

Explanation:

The English word "trajectory" comes from the Latin noun traiectoria, which itself derives from the Latin verb traicere (meaning "to throw across, to traverse"). Traicere is a compound of trans- ("across, beyond") and iacere ("to throw"). The Latin traiectoria referred to the act of throwing across, and this evolved in English to specifically mean the path of an object moving through space, retaining the core sense of a path created by something "thrown across" a space.

Answer:

"Trajectory" derives from Latin traiectoria, which comes from the verb traicere (a compound of trans- "across" and iacere "to throw," meaning "to throw across"). The Latin root's sense of a path created by moving/propelling something across space evolved in English to denote the specific path of a moving object.
