Tolkien discusses the elements of the word Sigelhearwan and related forms, as found in Old English manuscripts. Sigel can mean both "sun" and "jewel", and while the meaning of hearwa is unknown, he suggests that it is connected to devils and blackness. Tolkien writes that his tentative analysis shows that:
[g]limpses are caught, if dim and confused, of the background of English and northern tradition and imagination [...] Sigel may be taken as a symbol of the intricate blending of the Latin and Northern which makes the study of Old English peculiarly interesting and controversial.
 Relation to the legendarium
Tom Shippey has suggested that Tolkien's discussion of Sigelhearwan "helped to naturalise the 'Balrog' in the traditions of the North, and [...] to create (or corroborate) the image of the silmaril, that fusion of 'sun' and 'jewel' in physical form".
