'arrowheaded' originates from English, built from the compound 'arrowhead' (arrow + head) with the adjectival suffix '-ed'. 'arrow' comes from Old English 'earh' (Middle English 'arwe') meaning 'projectile shot from a bow', and 'head' comes from Old English 'heafod' meaning 'top' or 'head'.

'arrow' changed from Old English 'earh' to Middle English 'arwe' and eventually to modern English 'arrow'; 'arrowhead' was formed as a compound in Middle English, and the modern adjective 'arrowheaded' was formed by adding '-ed' to denote 'having or shaped like an arrowhead'.

Initially it meant 'having an arrowhead' or 'provided with an arrowhead'; over time it has come to be used primarily to describe shapes or formations that are 'shaped like an arrowhead' or 'forming a pointed front.'
