Haljala was attested in historical sources as
Halela in 1241,
Halgel in 1402,
Halligell in 1445, and
Haliel in 1447, among other spellings. The Finnish linguist
Lauri Kettunen analyzed the name as not ending in -
jalg 'leg, foot' (genitive -
jala), but with the suffix -
la. According to the linguist
Valdek Pall, the suffix -
la in place names is often preceded by a personal name, and Airi Kartano has compared personal names containing
Hal (such as
Hali(kko), and
Halli) with the word
hall 'gray(-headed), gray(-bearded)'. R. Alitalo has connected the meaning of Finnish place names containing
Hali (e.g.,
Halinen) to areas near water, which could also apply to Haljala due to its lake with many springs. ==Church==
