In English, dipthongs are represented by two letter combinations (digraphs). Of course, English being English, digraphs may represent more than one dipthong, and some dipthongs are represented by more than one digraph!
In English, the dipthong “//aʊ//” in IPA is represented by “ou” or “ow”, but is also used in the words “Maori”, “Mcleod”, “sauerkraut” and “umlaut”.
In Diinlang we try to improve on this, with each dipthong only being represented by a single digraph.
In the past, the dipthong represented by “//aʊ//” in IPA has been represented in Diinlang by the digraph “ou”.
Recently it has occurred to me that “//aʊ//” might be better represented by the digraph “au”. This will be more intuitive for users familiar with IPA. It also reduced the number of dipthongs in Diinlang that have digraphs beginning in “o-”.
