I pronounce "Grappel" as "Grapp-Pell" and others remarked that I sounded like I was trying to 'Frenchify' the name "Grapple" in a comical way, like how some people pronounce Target as "Tar-Jay". It was never my intention to Frenchify anything... I'm just trying to pronounce "Grappel" correctly and apparently it sounds Frenchie to some people. <shrug>
If I say "Grap-Pull" then I'm referring to either G1 Grapple (or any of its reissues) or United Grapple. But if I say "Grap-Pell" them I'm specifically referring to Reveal The Shield Solar Storm Grappel.
