Systematicity

The coincidence in modern tongues between harmony, as spoken of sounds, with any other concordance or systematicity— is one derived from ancient Greek sources and roots[…].

[…] but it is reasonable to see a certain amount of causal and functional integration as a hallmark of systematicity.

At times there is consistency to Yule’s headword spelling (e.g. long-a /aː/ is rendered au except when word final, where it is rendered a), but there is also inconsistency (e.g. short-a /ʌ/ is sometimes rendered a and sometimes u). My analysis indicates the lack of any overarching systematicity.
