The National Trust for Scotland has determined that the following are the correct terms for Scottish swords:

"claidheamh mor" - basket-hilted broadsword or "Claymore"

"claidheamh cuil" - basket-hilted backsword (single edged)

"claidheamh da laimh" - two-handed sword, often incorrectly called Claymore

The term "claybeg" is modern; there is no evidence of historic usage of "claybeg"....
