Reconstruction notesEdit

  • Kogan reconstructs *layliy- to account for the Ge'ez form, whereas Fox reconstructs the reduplicated form *laylay- and the triradical form *layl- as coexisting in Proto-Semitic. Al-Jallad argues in favor of the reduplicated form underlying all the attested reflexes.
  • A feminine by-form (likely a singulative) can be reconstructed at the level of Proto-Semitic, and underlies many of the descendant forms.
