What does problem mean?
A problem is a difficult situation, question, or puzzle that requires attention, investigation, or a solution. The word is extremely common in everyday speech and formal writing alike, appearing in expressions such as "solve a problem," "pose a problem," and "the underlying problem." It often suggests that obstacles exist and that action is needed, but it can also refer more neutrally to a question being considered. In phrases such as "no problem" or "What's the problem?" it may convey reassurance, curiosity, or impatience depending on context. Although an issue can sometimes describe a broader matter of concern, a problem more strongly implies difficulty or the need for resolution. In mathematics and logic, a problem is a proposition or question to be demonstrated, calculated, or explained. As a rare informal verb, to problem someone means to cause difficulty for them.

Where does problem come from?
The word comes from Ancient Greek próblēma, meaning "question" or "problem," from probállein, "to put forward," formed from pro-, "forward," and ballein, "to throw." English borrowed the term through Latin problema in the late Middle English period. Its derivatives, including problematic, problematize, and problemist, preserve the same history of presenting something for examination or dispute.
