Although these meanings share a common element, that common element is an abstraction with no existence outside the mind; rather, the mind abstracts it, for they never used these particles without qualification.
The grammarians then saw that this shared meaning bore some resemblance to the physical objects the Arabs call “containers,” so they called it a “container.” This is a literal usage within a particular technical convention, not the language spoken by the Arabs and used in the Quran and hadith. The same applies to the rest of their terminology, such as verbal subject, object, circumstantial qualifier, adjective, specifying complement, inflectable and indeclinable forms, nominal subject, predicate, and the like.
