Forum:Dicard 1 card

some card says something like: "discard 1 monster/card".

i want to know from where i can discard them. my side of the field, and/or my hand, and/or my deck.

and i know sometimes the card says "discard 1 card/monster from your hand/your side of the field/your deck", but most of the times they say it without the "your hand/your side of the field/your deck".
