'OO' is neither a digraph nor a diphthong; it's a common misconception. In terms of phonetics, a digraph is a pair of letters that represent one sound, while a diphthong is a complex vowel sound within a single syllable, involving a glide from one vowel sound to another. 'OO' can represent different sounds as in 'book' or 'moon', but strictly speaking, it's considered a pair of vowels forming part of a vowel team in English, which can sometimes function similar to a diphthong in pronunciation.
