+## What makes something a target? [#what-is-a-target]
+
+Any game object, player, or zone that a spell or ability chooses to affect is a target (<Rule number="352.6" />), and must be declared when putting that spell or ability on the chain (<Rule number="352.7" />).
+
+Card text rarely uses the word "target" or "choose" explicitly - most of the time targeting is implied, as in "Kill a unit" or "Move a friendly unit."
+Abilities that reference "when you choose" a game object, such as [Irelia, Fervent Blade](https://riftbound.leagueoflegends.com/en-us/card-gallery/#card-gallery--sfd-057-221)'s "When you choose or ready me, give me +1 Might this turn," are specifically triggered when being targeted.
+
+When in doubt, assume it is a target - the list below covers the only situations where it is not:
+
+- **It is in a private zone** (hand, deck, etc.) (<Rule number="352.10.a" />). e.g., "You may play a unit from your hand" does not target a unit - it merely lets you play one.
+- **It is only a location requirement for another target** (<Rule number="352.10.b" />). Words like "at a battlefield" narrow down which objects are valid targets; the battlefield itself is not a target - unless the effect lets you choose *which* of several battlefields to affect, as in "Kill all units at a battlefield."
+- **It is part of a trigger condition, cost, or replacement effect** (<Rule number="352.10.c" />, <Rule number="352.10.c.1" />). Objects referenced in "when X happens" conditions, payment costs (see also [When do I pay costs within instructions using "may"?](/general-rules/abilities#costs-within-instructions)), or "instead" effects are not targets. e.g., the dying unit in "When a friendly unit dies, kill a gear" is not a target - only the gear is.
+- **There is no real choice involved** (<Rule number="352.10.d" />). If an effect applies to every object meeting a description rather than a specific one you pick, nothing is targeted. e.g., "Kill all units at battlefields" targets nothing because you are not choosing among individual units.
+- **Another player makes the choice** (<Rule number="352.10.e" />). Targeting requires that *you* make the choice. e.g., "Each player kills a unit they control" does not target - each player picks their own unit when the spell resolves.
+- **The instruction uses "must"** (<Rule number="352.10.f" />). This signals the choice is made on resolution rather than upfront. e.g., "You must recycle one of your runes" does not target, whereas "Recycle a rune you control" does.
+
+## Does "you may" mean I choose the target at resolution? [#may-targets-at-resolution]
+
+No.
+
+Targets are always declared when putting a spell or ability on the chain (<Rule number="352.7" />), not at resolution.
+If a "you may" effect involves choosing a game object, that choice is still a target and must be declared upfront.
+The "you may" means the effect is optional - you can decline to complete it on resolution - but it does not defer when the target is declared.
+
+<Callout type="idea" title="Example">
+	[Relentless Pursuit](https://riftbound.leagueoflegends.com/en-us/card-gallery/#card-gallery--sfd-184-221) reads "Move a friendly unit. You may attach an Equipment with the same controller to it. This turn, that unit has 'When I conquer, you may move me to my base.'"
+
+	When playing this spell, you must immediately declare both targets: the friendly unit to move and an Equipment to attach.
+	You cannot wait until resolution to decide which Equipment to name, and you cannot put the spell on the chain without a valid Equipment target at all.
+
+	The "you may" only means you can decline to complete the attach when the spell resolves - it does not make the Equipment target optional.
