problem

problem: [14] A problem is etymologically something ‘thrown forward’. The word comes via Old French probleme and Latin problēma from Greek próblēma, a derivative of probállein ‘throw forward’. This was a compound verb formed from the prefix pro- ‘forward’ and bállein ‘throw’ (source of English ballistic, emblem, parable, etc). Things that are ‘thrown out’ project and can get in the way and hinder one, and so próblēma came to be used for an ‘obstacle’ or ‘problem’ – senses carried through into English problem.
=> ballistic, emblem, parable, symbol
