Most Australian languages have two rhotics or r-like sounds: a retroflex approximant, as in American English, written ⟨r⟩; and a trill or flap (both of which are found in Spanish), written ⟨rr⟩.
De fleste australske sprog har to rullelyde (r-lignende) lyde: en retroflex approximant som i amerikansk-engelsk, der skrives r, og en trillelyd eller smæk-lyd (som begge findes i spansk), skrevet rr.
