3 The unit of measurement of dependency length A limitation of<cite> Ferrer-i-Cancho (2015)</cite> is that dependency length is measured in words. However, it could be measured in other linguistic units: syllables, morphemes, phonemes, etc. A higher level of precision might illuminate inconsistencies between the dominant order according to the criteria in Dryer (2013) and other orders that appear recurrently in particular circumstances.
