Dyslexia and Reading Terms & Definitions
Alphabet principle is the letter combination, as well as individual letters, which constitute symbols that are used to represent speech sounds. The letters and combinations are based on systematic and known relationships between written letters and spoken words.
Digraph is one sound resulting from the combination of two letters (e.g., ph or ey). In the English language, there are many digraphs made up of both consonants and vowels.
Diphthong is a single syllable speech sound (e.g., the combination of two vowels in words such as boy or may) that begins at or near the point of articulation of one vowel and proceeds to the place of another vowel.
