Definition my friend, without definition I can't understand you

In written work, please provide sufficient (if not redundant) amount of definition/explanation of terms used in the writing. If a writer fails to do so, it will be very difficult for readers to understand what you are trying to say.

In a conversation, at least when the listener can't understand a term/expression introduced into the speech, he/she can still stop the speaker on his/her track to ask about the ambiguous or foreign term (or expression) just used.

So, when someone is talking about "input tax", "residual supplies, claim, and "De Minimis Rule", a Science person like me only hear tax input, what supply leftover, claim, minimal rule, what? It make no sense.
