Prevenient is an adjective that means preceding 

The Latin prefix P-R-E means ‘before.’ You can find it in a number of English words like prevent, preheat and prefix. The word venire (vuh NEAR ay), also from Latin, means ‘to come.’ To come before something means to be prevenient to it. Here’s an example of it in use:

I’m not sure what happened on the prevenient day, but on Friday, there was a huge argument at the office over Jane’s parking space. Since I had missed work on Thursday, I can’t say for sure what came before the fight.
