An example of phonetic is the word "dad" being spelled the way it sounds.
The differences between the sounds represented by p in “tip” and “pit” are phonetic, since substituting one for the other would not change the meanings of the two words.
Origin of phonetic
- New Latin phōnēticus representing speech sounds from Greek phōnētikos vocal from phōnētos to be spoken from phōnein to produce a sound from phōnē sound, voice bhā-2 in Indo-European roots
