The verb assume means to take something upon without any proof. Some synonyms are to suppose, or take for granted. Assume can also mean to begin to have some power or huge responsibility. Assume originated from the Latin word ad (towards) + sumere (take) or assumere.


Presume is synonymous with assume but the difference is that it is based on some probability. Presume has its roots from the Latin praesumere meaning ‘anticipate’.
