Here's how it works:
* -mittere (Latin root)
* -mit (suffix, shortened form)
Examples of words with the "-mit" suffix:
* Submit (to send oneself under)
* Transmit (to send across)
* Emit (to send out)
* Commit (to send oneself to a task)
While Greek has some words with "-mit" in them, like "transmit" and "permit", these are borrowed from Latin.
