From earlier *sämä; cognate with Proto-Samic *sāmē.[1][2][3][4] Further etymology uncertain. Several theories have been proposed (mostly incompatible with the currently accepted proto-form *sämä), but none have been accepted.
One theory, proposed by Koivulehto among others, stated that the word originated from Baltic *šāma-, via Pre-Proto-Finnic *šämä from Proto-Balto-Slavic *źemē (“ground”), from Proto-Indo-European *dʰéǵʰōm; the vowel correspondences being explained by reborrowing back and forth, possibly with a late Proto-Germanic borrowing. The progress would have roughly been Proto-Indo-European *dʰéǵʰōm > Proto-Balto-Slavic *źemē (“ground”) → Pre-Proto-Finnic *šämä (> Proto-Finnic *hämä, Proto-Samic *sāmē) → Proto-Balto-Slavic *šāma- (or *sāma-, in view of Latvian sāms (“Finn, Öselian (inhabitant of Saaremaa)”), Latvian sāmenis (“northern wind”) and dialectal Lithuanian sómenis (“northwestern wind”), unless the Lithuanian word is a borrowing from Latvian) → (through Proto-Germanic?) Proto-Finnic *sooma.[5] Koivulehto originally proposed that Proto-Balto-Slavic *šāma- would have been borrowed through Proto-Samic specifically.[6] However, this theory assumes an improbable back-and-forth chain of borrowings, relying on too many unconfirmed assumptions, and thus has to be rejected (especially in light of current information).[7][4]
Another theory proposed an origin from an earlier supposed *ćoma (“human”), either borrowed from Proto-Indo-European *ǵʰmṓ or from pre-Proto-Balto-Slavic *ǵʰom-yā-.[7] With the new information that the earlier form is actually *sämä, these too have to be rejected.[3]
Antique ad-hoc proposals that the word is derived from *soo-maa (literally “fen land”) or *soo-neemi (literally “fen cape”), or from *soomu (“(fish) scale”) have long been considered untenable.
