The two-handed claymore seems to be an offshoot of Early Scottish medieval swords which had developed a distinctive style of a cross-hilt with downsloping arms that ended in spatulate swellings. The spatulate swellings were frequently made in a quatrefoil design.
The term claymore is an anglicisation of the Gaelic claidheamh mòr "great sword", first attested in 1772 (as Cly-more) with the gloss "great two-handed sword".The sense "basket-hilted broadsword" is contemporaneous, attested in 1773 as "The broad-sword now used [...] called the Claymore, (i.e. the great sword)." observes that the latter usage is "inexact, but very common". The 1911 Encyclopædia Britannica likewise judged that the term is "wrongly" applied to the basket-hilted sword.
