In what follows we describe how root allomorphy is annotated in the Database.

Root allomorphy is annotated in two columns:

• Column Root allomorphy (y/n): 1 is enetered if there are any unpredictable difference.
• Column Root allomorphs (list): The allomorphs of a verb are listed for verbs that exhibit root allomorphy.

Root allomorphy is taken to be any unpredictable difference between the finite and non-finite form of the verb.

Ignore defective verbs for the purposes of this column. Compare the finite and the non-finite forms of the verb (and not all verbs that have the same root, ie. compare vzeti with vzamemo; jemati with jemljemo; but not vzeti with jemati).

Column Root allomorphy (y/n): Enter 1 if there is any unpredictable difference. Column Root allomorphs (list): Enter the allomorphs

Cases of predictable/productive phonological allomorphy (such as pisati-pišem) are *not* considered as cases of root allomorphy here (ie. they get a 0 in the Root allomorphy (y/n)-column). Consider examples below.

Examples of root allomorphy: početi-počnemo brati-beremo poslati-poš(a)ljemo ići - idem hoteti - hočemo hteti - hoćemo žvakati - žvaćemo doći - dođemo obiti - obidemo

Examples of things that we don't count as stem allomorphy: peći-pečemo (kt to ć is productive) piti-pijemo (j epenthesis is productive), obuti-obujemo (j epenthesis is productive), gristi-grizemo (voicing assimilation is productive) pisati-pišemo (pisjemo to pišemo is a productive rule) krasti-krademo (kradti to krasti is a productive rule) kupovati-kupujemo (ova-uje is counted as a theme vowel combination).
