• Sacrum — An obsolete, rare graphic variant or faulty transcription for the sacrum bone (os sacrum); the large triangular bony piece located at the base of the vertebral column, formed by the structural fusion of the five sacral vertebrae, articulating laterally with the iliac bones to close the pelvic girdle.
• Regional bird name — A rare regional name used in certain folk dialects of the Balkan area to designate a species of nocturnal bird of prey or a type of small migratory bird; a word structurally preserved in the archaic rural lexicon. This term retains nuances of traditional avian onomastics, being very rarely used outside ethnographic texts or local dialectology glossaries.

• Additional — An obsolete graphical and phonetic variant of the word 'adăugător', used in 19th-century administrative, legal, or theological texts. As an adjective, it describes an element, numerical factor, clause, or component possessing the property of bringing an addition, magnification, completion, or structural expansion to an existing base.
