Great quiz! One thing I am not completely sure about is the word gaging. Google says it’s a word, but that the more common spelling would be gauging. I’ve personally never seen it spelled that way, but it is a valid spelling. I just thought I’d bring that to your attention if you didn’t already know.
I've accepted it as it begins with G and has 8 letters. It doesn't fit, but it means the same, and if you didn't have any letters you could think that. It's only a type in though.
Words: A, B, C, D, E, F, G, H, I, S
Others: Colours, Numbers (mini)
Very odd to see this word spelt this way!
