What word am I thinking of?

[Manang Muyang]

Don't make me strike out, please. There must me an N there!

[Alice Heritage]

Yikes, sorry, no N. When you were on unusual you went with K, which scores 5 points in Scrabble. I can reveal that the first letter is a little unusual - it's one of the 4 pointers in Scrabble.

[Manang Muyang]

Okay, I hope this one gets a yes. W for the win!

[Alice Heritage]

Yay! W _ _ _ _ _ _

[Manang Muyang]

Hallelujah! H should be there too!

[Alice Heritage]

Sorry, no H.

[Manang Muyang]

Oh, O then?

[Alice Heritage]

Oh no, no O.

[Manang Muyang]

E should be there! Come on, E!

[Alice Heritage]

Eek! Afraid not ... try the vowel before it maybe ...

[Manang Muyang]

Your word is a real puzzler! 'A' must surely be there.

[Alice Heritage]

That's the one!
WA _ _ A _ _

[Manang Muyang]

Is there a Y in that intriguing word?

[Alice Heritage]

Oh yes:

WA _ _ A _ Y

[Gravy]

I'm going to guess an 'S', simply for the fun of it!
