Advice refers to an opinion offered in an effort to be helpful. It commonly describes deliberate consideration; knowledge, in language about financial transactions executed by formal documents, an advisory document, and in commercial language, information communicated by letter; used chiefly in reference to drafts or bills of exchange, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to a communication providing information, such as how an uncertain area of law might apply to possible future actions, counseling to perform a specific legal act, and counseling to perform a specific illegal act, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Advice as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Additional shades of meaning include in aspect-oriented programming, the code whose execution is triggered when a join point is reached, which reinforce how the category can stretch across adjacent but still recognizable uses of the same term.
