There are a few dozen nominals ending in a consonant which form another
small sub-group. The two final sounds of the basic form are generally -el or -
en. The partitive singular is made from the basic form. The inflectional stem
adds an -e- (which is dropped before the plural -i-).
Most of the words inflected like avain ‘key’ are derived with the ending
-in (cf. §93.1). The stem alternates between -in- and -ime-, and the
partitive singular is made from the basic form.
