For example, it is common for the manuscript texts to contain a mix of dialectal features not found in any single modern dialect. The language of the manuscripts also contains a higher number of Arabic words than the modern spoken form, a phenomenon that has been called arabisme poétique.[2] Other characteristics of manuscript verse text, which are probably adopted from oral conventions, are the use of plural verb forms instead of singular forms, uncommon plural nouns formed with the prefix ida, use of stopgaps such as daɣ “again”, hann and hatinn “lo!”, etc. These conventions can be linked to the need to make the text conform to fixed metrical formulae.
