So the Info Magazine in Unite calls it a 'Great Sword', the Weaponsmith calls it a 'Great Swd'. Then again the info magazine and Weaponsmith calls our favourite two-sword weapons 'Dual Blades' and frankly after calling them 'Dual Swords' all these years, screw that. Even more weirdly SnS is just 'Sword' according to both the same sources...

Long Sword is also two words.
