p

The sixteenth letter of the English alphabet and the twelfth consonant, representing the voiceless bilabial plosive sound /p/. As a grapheme, 'P' is produced by briefly stopping airflow with both lips and then releasing it without vocal cord vibration. It is notable for the silent 'p' in initial clusters like 'psychology' and 'pneumonia', a feature inherited from Greek. It functions as an abbreviation for page, a designation for parking, a symbol for phosphorus in chemistry, a musical dynamic marking for soft, and the sixteenth item in a sequence.
