Words only found in one Maiden song.

[Ariana]

What about honestly?

 

[Moon Child]

Dammit! That's right and I even posted 'goose' earlier so I should have known.

 

[The Flash]

I don't think that'd count since there's honest on Wasting Love.

 

[Ariana]

Oh, well! Steve lost the game.

 

[CriedWhenBrucieLeft]

"Wedding" & "Steve"

 

[CriedWhenBrucieLeft]

Sherriff, Huddersfield, flies, freeway, briefcase, lunch, Juanita, Chelsea...

 

[Ariana]

You didn't read the whole thread, did you?

 

[CriedWhenBrucieLeft]

I did actually, but thought the first game was better... then I just started typing random words.

Still, "Steve" doesn't come up in many songs!

 

[Dr. Eddies Wingman]

But does anybody other than the Long-Distance Runner experience loneliness?

A certain kosmonaut? The loneliness is hard to bear ...

 

[Forostar]

Well well! Lots of hard work here!

I don't think that'd count since there's honest on Wasting Love.

Don't want to nitpick but I intended to be quite clinical about this. For once, this is not about the meaning of the words, or about etymology. It's about presence of the words, exactly as they're formed. The exact presence, the use of the word, the form is what I meant rather than its context/meaning whatever.
So honest and honestly are different words in this context. So are fulfill and fulfillment and caught and catch.

Besides these I also found these unique words in Caught Somewhere in Time (unless I'm mistaken):

offer
refuse

 

[Ariana]

We're back in the game? Yay!

 

[Minty_Fishbowl]

I'm surprised the OP didn't mention how much Maiden uses the word/concept of Dreams in their songs.

Seriously, you could make a drinking game out of it.

 

[mckindog]

And we will!

 

[Perun]

Yeah, as a warm-up to that game of downing a shot whenever the word "fight" pops up in Manowar's Fighting the World.

 

[Dr. Eddies Wingman]

Or the word "oy" in AC/DC's "TNT"?

 

[Maidenvana]

Or "die" in Die With Your Boots On

 

[Perun]

Or better yet, the "Rainbow" game with any given Dio album.

 

[Ariana]

Are you going to play the game or just talk?

 

[Perun]

на сдорове!

 

[Ariana]

Russian? Meh...
