Ẹsinmirin

• Ẹ̀sìmìrìn

Possibly from ẹ̀- +‎ sìnmìrìn, which in term may be constructed to Proto-Yoruboid *ò-sĩ̀mĩ̀lì. Likely related to Igbo òsìmìlì (“river”), Igbo Òsìmìlì (“Niger river”), and Igala òhìmìnì (“a major river”). While the term only exists as the name of a mythological river found in an oral story, it may have originally been used as a term for any large body of water, similar to the Niger river, as the Proto-Yoruboid, and then Proto-Yoruba speakers migrated into Yorubaland and came upon many different large bodies of waters. The term likely was used in reference to the Niger river, the major body of water Proto-Yoruboid speakers would have known and likely worshipped. It is potentially an older cognate with Igbo mmiri (“water”) and thus potentially a Doublet of omi.
