Discard
Discard refers to the act of moving a card from the hand, sending it to the Graveyard as a result, either as a cost or by an effect (that use this term), or due to to hand Size Limit during the End Phase.
A card being discarded does not necessarily go to the Graveyard. Although this is normally the case, cards like "Macro Cosmos" will send the cards to the Banished Zone instead; however, the card is still considered as being discarded.
