A store of words; (in later use esp.) the vocabulary of a person, group, or language.

Lines to be Stickered on the Rear Windshield as the Wee Cherub Explores her Power of Speech 

Gave she you slick
And sweet music,
Each note heard scored
By her wordhoard.

"Baa," the cat neighed,
"Oink," the gnat brayed,
"Moo," the bird roared
In her wordhoard.

Rebbwue bowngeen,
And all nouns seen
With "Ooo!" stirred poured
In her wordhoard.

In her wordhoard,
Every third-floored

Window was aap,

And applause cwaap.

The alphabet 
She knows not, yet
Undeterred oared
Through her wordhoard.

If 'ver I sense

Ennui, I fence.

My preferred sword
Is her wordhoard.
