For example, if the PAST and PRES;PCPLE forms in P are x 1 +ed and x 1 +ing respectively, we do not want to infer a form x 1 +x 2 +n for PAST;PCPLE because the stem corresponding to P has only one variable x 1 .
we restrict the vote to paradigms which have the same number of variables (x i s) as P .
