Alloglottography

For Iranian-speaking scribes, alloglottography would be rather preposterous.

With a narrow definition of alloglottography, one that sees language learning via speech as inherent to scribal education and scribal life, I could definitely agree.

Some texts extend alloglottography over entire clauses or even a whole text.

Such narratives almost inevitably lead to the postulation of neat trees of dialect divergence out of the homogenous standard of an assumed prestige koiné, and to widespread neglect of colloquial, technical, or ritual speech, of loanwords, alloglottographies and similar phenomena.
