From -a- +‎ -lla (like in -alle, -alta). The initial component was not originally simply a vowel, but was preceded by a consonant. The preceding component was:

• *-ga-, in monosyllabic pronominal stems like täällä and siellä (as well as the corresponding forms with -alta). in which case it may be -ka (like in täkä- > *tägällä > täällä).^[1]
• *-ja- (probably, or *-ga-), in most forms on polysyllabic stems. In dialects, forms like kaikkijalla, kaikkihalla (kaikkialla) and toisahalla, toisajalla (toisaalla) are found. According to SKRK, the first component may be the same suffix -ja seen in some place names (Proto-Finnic *-ja (denominal suffix), unrelated to the deverbal agent noun suffix -ja).^[1] Alternatively, Mantila (1992) proposes that the consonant in this variant was initially *-g-.^[2]
• *-ha-, in alhaalla and ylhäällä (as well as the corresponding forms with -alle, -alta), and connected with -hinen.^[1]
• *-da-, in istualla(an) and seisaalla(an) (as well as the corresponding forms with -alle, -alta), which is probably related to the first infinitive ending (Proto-Finnic *-dak).^[1]
