Some purists (usually philosophers) object to the use of "beg the question" to mean "raise [or pose] the question." Philosophers don't own this expression, and they come across as arrogant jerks when they object to its use by nonphilosophers. Like "negligence" in law and "mass" in physics, it has both a generic, everyday meaning and a specific, technical meaning. The context almost always disambiguates. My philosophical colleagues should ease up. Meaning is use.
