the agent-deriving suffix may have the following 16 forms: -cı, -ci, -cu, -cü, -çı, -çi, -çu, -çü, -ıcı, -ici, -ucu, -ücü, -yıcı, -yici, -yucu, -yücü), and sometimes there is no overt suffix (as in the third person singular copula, which is a zero morpheme).
there has been no apparent progress in the unlabeled attachment score.
