merestä
Merestä is the elative singular form of the Finnish noun meri, meaning the sea. The elative case marks origin or movement away from a source, so merestä translates roughly as “from the sea” or “out of the sea.” It is commonly used to indicate that something originates in or has been retrieved from the sea, and it can modify a following noun or appear with verbs of extraction.
Usage examples illustrate its function. Sukeltajat toivat merestä simpukoita. (Divers brought shells from the sea.) Muinaisjäännös
