Open any move's info screen and there are two icons sitting next to each other: a Type icon (the familiar colored badge for Fire, Water, Psychic, and so on) and a Category icon. The Type icon gets all the attention because of the weakness chart, but the Category icon is doing just as much work, and it's the one people misread most often. Here's what the three of them mean.

Physical. Shown as a pair of crossed swords (or a solid fist in older game generations). A Physical move calculates its damage using the attacker's Attack stat against the defender's Defense stat. Moves like Earthquake, Close Combat, and Waterfall all fall here, and anything that boosts Attack, like Swords Dance, a Choice Band, or the ability Huge Power, only helps Physical moves land harder.

Special. Shown as a swirl or burst icon. A Special move calculates its damage using the attacker's Special Attack stat against the defender's Special Defense stat instead. Fire Blast, Surf, and Shadow Ball are all Special. Special Attack boosts, whether from Nasty Plot, Choice Specs, or an ability like Solar Power, do nothing for a Physical move and everything for a Special one.

Status. Shown as a star (or a circle with a horizontal line through it in older generations). A Status move doesn't deal direct damage at all, so it has no Attack-versus-Defense or Sp. Atk-versus-Sp. Def calculation to run. Instead it does something else entirely: Swords Dance and Nasty Plot raise stats, Toxic and Thunder Wave inflict a status condition, Stealth Rock sets up a hazard, Recover restores HP. Since there's no damage roll, a Status move's own Type mostly matters for accuracy interactions, ability immunities (a Ground-type is immune to a Status move that happens to be Electric-type, for instance), and secondary effects like Sandstorm, but not for an Attack-stat calculation of any kind.

Why older players still get this wrong. Up through Generation III (Ruby, Sapphire, Emerald, FireRed, LeafGreen), category wasn't assigned per move at all, it was assigned per Type. Every Fire, Water, Grass, Electric, Ice, Psychic, Dragon, and Dark move was automatically Special, and every Normal, Fighting, Poison, Ground, Flying, Bug, Rock, Ghost, and Steel move was automatically Physical, full stop, no exceptions. That meant a physical attacker with a Fire-type move was stuck using its (often much weaker) Special Attack stat whether that made sense for the Pokemon or not.

Generation IV's Diamond and Pearl in 2006 introduced the Special Split, which is exactly what it sounds like: category got decoupled from Type and assigned to each individual move instead. Suddenly Earthquake stayed Physical (as expected, since it's Ground-type) but so did Flare Blitz and Brick Break in ways that made more sense for their respective Pokemon, and every generation since has kept moves and category separate. If you played the older games and still instinctively think "Ice moves are Special," that instinct is two decades out of date, but it made total sense back when it was true.

A few moves that break the mold on purpose. A handful of newer moves complicate the "just check the icon" rule further. Photon Geyser, Light That Burns the Sky, and Tera Blast (when a Terastallized Pokemon has certain Tera Types) all compare the user's Attack and Special Attack stats and use whichever is higher for the actual damage formula, regardless of which category icon the move displays. Shell Side Arm goes a step further and compares the user's Attack/Defense split against the target's before deciding whether to hit as Physical or Special that turn. These are rare exceptions rather than the norm, but they're worth knowing before you assume a move's icon tells the whole story.

Where to actually check this. In any mainline game, highlighting a move on the summary or battle screen shows its Type and Category icon together. If you're theorycrafting outside of a save file, our Damage Calculator already accounts for category when it runs the numbers, and the Pokedex tool breaks out physical and special attacker leanings on a Pokemon's stat page so you can tell at a glance which category actually plays to its strengths.
