CASUAL/ROUGH demonstrative

そいつ is the rough/casual equivalent of それ (that) or その人(ひと) (that person). It belongs to the こそあど demonstrative system.

こそあど DEMONSTRATIVES (ROUGH):

  • こいつ - this guy/thing
  • そいつ - that guy/thing (near listener)
  • あいつ - that guy/thing (far from both)
  • どいつ - which guy/thing

Formality note

そいつ is very casual and can sound rude when referring to people. Avoid in polite conversation. Use それ/その人(ひと)/その方(かた) instead.
