This didn’t come as an email, but I discovered it while looking up the meaning of a Greek word and thought it was a useful word to note down:
The ‘did you know’ section on the same webpage reads:
Obviate derives from Late Latin obviare (meaning “to meet or withstand”) and Latin obviam,which means “in the way” and is also an ancestor of our adjective “obvious.” “Obviate” has a number of synonyms in English, including “prevent,” “preclude,” and “avert”; all of these words can mean to hinder or stop something. When you prevent or preclude something, you put up an insurmountable obstacle. In addition, “preclude” often implies that a degree of chance was involved in stopping an event. “Obviate” generally suggests the use of intelligence or forethought to ward off trouble. “Avert” always implies that a bad situation has been anticipated and prevented or deflected by the application of immediate and effective means.
