Homophones sound the same but are different words.
Sometimes they sound the same only in certain regions.
For me aunt is not a homophone of ant,
but more a homophone of aren't .
For some in the Southern states of the USA.
aunt and ant may be homophones.
Some words are pronounced as homophones
by some native speakers but not others. Some words are
global homophones and are pronounced the same
all over the English speaking world.
