Digraphs

The consonant digraphs in _ are utilised for two main reasons, which are compensation of sounds (particurarly before back vowels) and marking aspiration of some consonants (which makes them in fact phonemes), that later turned into fricatization.

The digraphs regarding the marking of aspiration for making new derived phonemes are of portuguese origin in terms of usage. They see a consonant followed by "h", which marks now fricatization. Eventual palatization of the fricatizated consonant in canceled and the consonants mantain their voiced or voiceless status. The digraph(s) is formed with the letters: b, g, d, k, p, q, r, t. All represent the fricative that takes place in the same place of articulation in the mouth as the plosive (or rhotic), apart from the digraph "rh", which instead represents a voiced uvular fricative, sound of portuguese origin later adapted into the aspiration sistem.

The fricatization of these eight consonants creates four voiceless/voiced pairs of new phonemes, being bilabial, dental, velar and uvular. As bilabial fricatives are close to already present labiodentals, uvulars are also very near velars. Distinguishing these similar sounds although (at least by language knowledge rather than pure execution) is necessary for the comprehension and construction of syntacts.
