(1) =ne= is added chiefly to dissyllables, also to trisyllables in =ea=
(=eä=), whose final =a= (=ä=), and sometimes =o=, changes to =e=. The
verb so formed is conjugated according to the third conjugation, and
the syllable =ne= altogether disappears in the infinitive, which ends in
=eta=. =Aleta= (present =alenen=) _to sink down_; =musteta=, _to become
black_; =lähetä=, _to draw near_; =pimetä=, _to grow dark_.
(2) =a= or =ä= is added mostly to dissyllabic roots ending in =i=, which
changes to =e=; if added to roots ending in =a=, this vowel generally
becomes =o=. It is also added to trisyllables in =ea= (=eä=). =Soeta=,
_to become blind_ (=sokea=).
A small number of verbs are formed from adjectives by the addition of
the suffix =ksi= or =ksu=, before which =a= and =ä= are often changed
to =e=. These verbs, sometimes called _censitive_, express the light in
which something is regarded. =Halveksia=, _to hold cheap_ (=halpa=);
=hyveksiä= _or_ =hyväksyä=, _to find good_, _to approve_; =pahaksua= _or_
=paheksia=, _to find bad_, _to be angry at_; =väheksiä= _or_ =vähäksyä=,
_to find small or despise_.
