Easy to mix with look-alikes

The spelling risk for Sif is neighbouring look-alikes ("so", "SS", …), not just typos; it is aproper noun pronounced /sɪf/. Frequency #49,636 among 6,566 “S” headwords. Gloss: "A golden-haired goddess associated with earth, mother of Ullr and wife of Thor.".

Sif has no tracked misspelling variants, typically a sign the spelling maps closely to how the word sounds. It also participates in 20 confusable-pair relationships, "so", "SS", "SP", and more, a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: From Old Norse, from sif (“kindred, kinswoman”), from Proto-Germanic *sibjō; see also Old English sibb (“kinship”) (whence Middle English sib (“having kinship; kinsmen”), whence English sib, sibling), German Sippe (“tribe”). The correct English form is Sif, spelled S-I-F.
