IPA: //trænˈzɪtɪvnəs//
KK: /trænˈzɪtɪvnəs/
The quality of a verb that requires a direct object to complete its meaning.
In English, the transitiveness of a verb determines whether it can take a direct object or not.
Transitiveness → It is formed from "trans-" (meaning across) and "it" (from Latin "ire", meaning to go) and the suffix "-ness" (indicating a state or quality). The word "transitiveness" refers to the quality of being able to go across or transfer an action from a subject to an object.
Think of 'going across' ('trans-') and 'to go' ('ire') to remember that 'transitiveness' describes the quality of transferring an action.
