Question

how can we show in writing that we are speaking of allophones? with example​

Answer 1

Respuesta:

For example, [pʰ] as in pin and [p] as in spin are allophones for the phoneme /p/ because they cannot distinguish words (in fact, they occur in complementary distribution). English-speakers treat them as the same sound, but they are different: the first is aspirated and the second is unaspirated (plain).
