-alla

Etymology
From (like in, ). The initial component was not originally simply a vowel, but was preceded by a consonant. The preceding component was:
 * , in monosyllabic pronominal stems like and  (as well as the corresponding forms with ). in which case it may be  (like in  >  > ).
 * (probably, or ), in most forms on polysyllabic stems. In dialects, forms like,  and ,   are found. According to SKRK, the first component may be the same suffix  seen in some place names (, unrelated to the deverbal agent noun suffix ). Alternatively, Mantila (1992) proposes that the consonant in this variant was initially *-g-.
 * , in and  (as well as the corresponding forms with, ), and connected with.
 * , in and  (as well as the corresponding forms with, ), which is probably related to the first infinitive ending.
