You can prepare an arcane spell ahead of time, just as a wizard does.
Prerequisite: Ability to cast arcane spells without preparation.
Benefit: Each day, you can use one or more of your spell slots to prepare spells you know, usually for the purpose of applying a metamagic feat to the spell-but without an increase in its casting time. Preparing a spell uses a spell slot of the appropriate level, and once prepared, that slot can't be used for anything else until the prepared spell is cast.
Normal: Spellcasters who cast arcane spells without preparation (such as sorcerers and bards) who apply a metamagic feat to a spell must cast it as a full-round action instead of a standard action.
