For example, [pʰ] (as in pin) and [p] (as in spin) are allophones for the phoneme /p/ in the English language.
From the Greek, other + sound , the term was coined by Benjamin Lee Whorf in the 1940s. In doing so, he placed a cornerstone in consolidating early phoneme theory. The term was popularized by G. L. Trager and Bernard Bloch in a 1941 paper on English phonology and went on to become part of standard usage within the American structuralist tradition.
