The system of relationships among the sounds of speech that combine into the basic parts of a language. The branch of language-study dealing with systems of sounds, especially in a particular language.
Spiritually: Jesus is The Word and The Alphabet (the A and Z or the Alpha and Omega in Greek, Rev. 21:5, 6)). In Him we live and move and have our very being. “Jesus” is the “system” of language: thoughts, sounds, letters, words, writings, and readings (John 1). Without Him, we would just be barking or mooing somewhere…phonology.
