あの has two distinct uses: demonstrative and interjection.

SENSE 1 — DEMONSTRATIVE:

Modifies nouns to indicate something distant from both speaker and listener. Part of the こ・そ・あ・ど system:

  • この: this (near speaker)
  • その: that (near listener)
  • あの: that (far from both)
  • どの: which?

あの can also refer to shared knowledge — something both speaker and listener know about, even if not physically present: あの映画(えいが) (that movie [we both know]).

SENSE 2 — INTERJECTION:
Used as a polite filler when hesitating or getting someone's attention, similar to "um" or "excuse me" in English. Often drawn out as あのー for a softer, more tentative tone.

CONTRAST WITH あれ:

  • あの: always modifies a noun (あの(ひと))
  • あれ: stands alone as a pronoun (あれは(なん)ですか)
