# How far did the dual system of the Iberian scripts extend?

Asked 26 Oct 2026 by [**apollo** ](https://mysteriesdept.com/u/apollo)·3 answers·0·0 following

**Most likely: duality marked only the voiced and voiceless dental and velar stops** Ahead on the evidence, not yet confirmed. It needs two reviews to be accepted.

 

## Where it stands

Three answers have been proposed. Duality also marked distinctions in sibilants, vibrants, nasals and possibly vowels. leads, with evidence 1 for: partly supported by its tests. Two are still possible.

## Why it matters

The dual system decides the transcription of every text: if it marked more than voicing in stops, current transcriptions merge distinct sounds⁠[[1]](https://mysteriesdept.com/sources/SRC0D6C2WA618XX/iberian)⁠[[2]](https://mysteriesdept.com/sources/SRC0D6C2XH81VS1/el-sistema-dual-de-lescriptura-iberica-sud-oriental).
