Instant subtypes are always single words and are listed after a long dash: "Instant — Arcane." Each word after the dash is a separate subtype. Instant subtypes are also called instant types. An instant subtype that's also a sorcery subtype is also called a spell type. Instants may have multiple subtypes. (You can find the complete list of instant subtypes under "Spell Types" in the glossary at the end of this document.)
