The runes were angular by necessity and design—curves were difficult to carve into wood grain, the knife or chisel producing straight cuts more easily than arcs, the character forms reflecting the constraints of carving technology.
The Elder Futhark was earliest widespread Germanic runic alphabet, containing 24 characters arranged in three groups (ættir) of eight. The name derived from first six runes—fehu, uruz, thurisaz, ansuz, raidho, kenaz—the mnemonic sequence facilitating learning, the grouping creating memorable structure. Each rune had phonetic value corresponding roughly to single sound, the system being fundamentally alphabetic rather than syllabic or ideographic, though individual runes also carried semantic associations beyond mere phonetic function.
The character design was economical—minimal strokes creating maximum distinctiveness, the forms being easily distinguished even when carved hastily or viewed in poor light. The vertical stave with angled branches attached was common pattern—the vertical providing reference line, the branches creating distinctions between characters, the asymmetry preventing confusion if inscription was viewed from different angles or in different orientations.
The evolution produced variant forms as Germanic languages diverged and writing needs changed. The Younger Futhark reduced character count to 16, simplifying system but creating ambiguities where single rune represented multiple sounds, requiring context to determine correct reading. The Anglo-Saxon futhorc expanded to 33 characters, adding new runes for sounds existing in Old English but not in other Germanic languages, the adaptation demonstrating that runic system was flexible, responding to linguistic changes rather than remaining fixed.
