[split] An interview with Stephen Bax - 1 to 1 substitution discussion

Ok, that makes more sense. Understood.
However, that could easily be explained away by a phenomenon like that which existed in medieval Spanish, where an initial /k/ was represented as a Qu. This same sound in the middle of words was written as /k/ or /cu/. 
Ie, Queda; cinCUenta. 
The middle Q tended to be expressed only in Arabic words such as alquiler; alquimista; arquitectura; until the 19 th century spelling reforms.
