eteläisin

Eteläisin is a Finnish adjective in its superlative form meaning “the southernmost” or “most southern.” It is used to indicate that something is located further south than others in a defined set, such as places, objects, or regions.

Form and usage: The word is formed from etelä- meaning south, with the adjectival suffix -inen to create eteläinen (southern), and the superlative suffix -in to create eteläisin (the southernmost). It agrees with the noun in number and case, for example: eteläisin saari (the southernmost island), eteläisin kunta (the southernmost municipality). In plural: eteläisimmät saaret or eteläisimmät kunnat (the southernmost ones). It can also appear as a predicate: Se on eteläisin (It is the southernmost).

Notes: The root etelä- is used broadly to refer to southern areas; eteläisin contrasts with pohjoinen (northern) or other directional terms. The word is common in geography, travel writing and statistics when describing extremes of latitude or regional positioning.
