A digraph or digram (from the Greek: δίς dís, "double" and γράφω gráphō, "to write") is a pair of characters used in the orthography of a language to write either a single phoneme (distinct sound), or a sequence of phonemes that does not correspond to the normal values of the two characters combined.
In Alphablocks, a digraph happens when two Alphablocks, either the same or different letter, are stuck together to make one sound. Usually the two letters that are stuck together in a digraph speak in unison.
There are also trigraphs which happen when three Alphablocks are stuck together to make one sound.
This is a list of digraphs and trigraphs that appear in the show. For the digraphs and trigraphs that do not appear in the show go here.
Q needs U to say her sound.
