What is the verb form of trajectory?

I looked up trajectorize but there's no such word.

    In English, nouns don't have "verb forms". Sometimes there are verbs with related meanings. Sometimes there are several different verbs with related but different meanings that can be formed from a noun. In this case I have no idea what meaning you think a verb form of "trajectory" would be. Do you mean "throw"? Or do you mean "follow a trajectory"?

    Who says trajectorise (/-ize) is not a word? It's sounds perfectly fine to me. Note that no dictionary can ever tell you something is not a word.

    Because it's absence from a dictionary implies that the word is very rarely used and so using it would cause confusion. I don't know what "trajectorize" is supposed to mean. Learners should use words that have currency in English, wherever possible.

Nouns in English don't have "verb forms".

"Trajectory" is the path that a projectile follows under gravity. To put something onto a trajectory you "project" it (stress on the second syllable). Or in simple language, you "throw" it.

You can also say "follow a trajectory". In English it is often better to use a phrase rather than a single verb.


According to Google.com, traject, meaning thrown across, was an earlier version.

Dictionary.com defines traject as

[ truh-jekt ]

verb (used with object) Archaic to transport, transmit, or transpose.

  • Note the usage note "archaic". This means that the word is not used in modern English anymore, and learners should not use this word (without good reason).
