Words be both exacting and vague: in that they often have more than one meaning. And, the intended usage might be "unclear". Based upon, the context a word be used among. That be the terms and meaning who surround it. Those might not clearly delineate. What be intended by the expression's speaker.
The term "aspect" is such a phrase, considering its specialized usage among software engineerings, computer scientists, and those who "organize and partition" concerns for computer programs. An "aspect" of a program is a concern who arises "implicitly". It is like those commands that record processing history or an operational profile. They always appear at certain parts of the internal module: during the first few opening or final few closing tasks. As such, their location and timing might be invoked "implicity". When, certain junctures among the "regular processing" be reached. They need not be "explicitly" called, by placing an instruction among the many places they would arise. As simple statement might be made among a global instruction-space. One who states: "This instruction shall occur [when]". And, it reliable nature, in terms of its appearance among the processing, guarantees this. That is a modern "aspect" among computing and software engineering, also known as, an aspectual-concern.
