Phono- comes from the Greek phone, which means "sound" or "voice". It appears in linguistics and audio technology vocabulary.
For someone studying English, this prefix is key. It tells you how sounds are produced, how to learn to read by connecting letters to sounds and what the smallest unit is that tells one word from another. One fact explains it all: English has about 44 different sounds and only 26 letters to write them, which is why phonetics is so important for pronouncing well.
Combines with Greek roots in linguistic and technological vocabulary:
Pronunciation: /ˈfoʊ.noʊ/. The ph is always /f/ in English words of Greek origin.
phono-/ˈfoʊ.noʊ/
Tap the button to hear how the prefix sounds. Each word in the table has its own audio.
"Phonetics" (phono- = sound + -etics = science): the physical science of speech sounds — production, acoustic properties, and perception. "Phonology" (phono- = sound + -logy = study): how sounds are organised and used within a particular language to create meaning. Example: English aspirated /p/ in "pin" vs. unaspirated /p/ in "spin" is phonetically different but phonologically the same sound.
A trick to remember it
Think of a phone carrying sound: phono- = sound. phonics, symphony.
