Writing systemA writing system is a method of visually representing verbal communication, based on a script and a set of rules regulating its use. While both writing and speech are useful in conveying messages, writing differs in also being a reliable form of information storage and transfer. Writing systems require shared understanding between writers and readers of the meaning behind the sets of characters that make up a script.
SeaxSeax (ˈsæɑks; also sax, sæx, sex; invariant in plural, latinized sachsum) is an Old English word for "knife". In modern archaeology, the term seax is used specifically for a type of small sword, knife or dagger typical of the Germanic peoples of the Migration Period and the Early Middle Ages, especially the Saxons, whose name derives from the weapon. These vary considerably in size. In heraldry, the seax is a charge consisting of a curved sword with a notched blade, appearing, for example, in the coats of arms of Essex and the former Middlesex.
Fibula (brooch)A fibula (/ˈfɪbjʊlə/, plural fibulae /ˈfɪbjʊli/) is a brooch or pin for fastening garments, typically at the right shoulder. The fibula developed in a variety of shapes, but all were based on the safety-pin principle. Unlike most modern brooches, fibulae were not only decorative; they originally served a practical function: to fasten clothing for both sexes, such as dresses and cloaks. In English, "fibula" is not a word used for modern jewellery, but by archaeologists, who also use "brooch", especially for types other than the ancient "safety pin" types, and for types from the British Isles.
Runic magicThere is some evidence that, in addition to being a writing system, runes historically served purposes of magic. This is the case from the earliest epigraphic evidence of the Roman to the Germanic Iron Age, with non-linguistic inscriptions and the alu word. An erilaz appears to have been a person versed in runes, including their magic applications. In medieval sources, notably the Poetic Edda, the Sigrdrífumál mentions "victory runes" to be carved on a sword, "some on the grasp and some on the inlay, and name Tyr twice.
Proto-languageIn the tree model of historical linguistics, a proto-language is a postulated ancestral language from which a number of attested languages are believed to have descended by evolution, forming a language family. Proto-languages are usually unattested, or partially attested at best. They are reconstructed by way of the comparative method. In the family tree metaphor, a proto-language can be called a mother language. Occasionally, the German term Ursprache (from Ur- "primordial, original", and Sprache "language", ˈuːɐ̯ʃpʁaːxə) is used instead.
