Prepossessing is an adjective that means creating a favorable impression.
The Latin word possidere (pose ee DARE ay) means ‘to hold.’ From this we get the word ‘possess’ which maintains the meaning of its Latin ancestor. By adding the prefix P-R-E, we get get the word preposses, which is a synonym of ‘prejudice’ as in ‘I was hoping the mayor’s speech didn’t prejudice your opinion.’ A prepossessing individual prejudices our opinion in a favorable way.
Having a prepossessing nature is always a big plus in the political world. Voters will often overlook many mistakes from people who make a favorable impression.
