Diagnostic Feature Reference
Orthographic markers used for chronological classification

Period | Feature | Explanation
--- | --- | ---
Archaic | K before /a/ | K/C/Q tripartition diagnostic of 7th–5th century scripts
Archaic | No F | F reintroduced after c. 400 BCE; absence suggests earlier date
Classical | C dominant | After c. 500 BCE, C replaces K and Q as general velar stop
Classical | Aspirates (θ, φ, χ) | Aspirated consonants become more consistent in Classical orthography
Late | F present | F from Latin /f/ appears in late Etruscan as labiodental fricative marker
