Raymonds run

ISignify- denote or connote
“I don’t think you’re going to win this time,” says Rosie, trying to signify with her hands on her hips all salty, completely forgetting that I have whupped her behind many times for less salt than that.
When the bell rings once it signifies that it's break, when the bell rings twice that signifies that it's lunch time.
Prefer-to like better
I’m ready to fight, cause like I said I don’t feature a whole lot of chit-chat, I much prefer to just knock you down right from the jump and save everybody a lotta precious time.

Hustle-move energetically or busily
And I don’t have to earn my pocket money by hustling; George runs errands for the big boys and sells Christmas cards.
There was a big hustle to go to the mall because there was a massive sale

Periscope-an instrument providing a view of an obstructed field
He looks around the park for Gretchen like a periscope in a submarine movie.
The captain looked through the periscope to see if the enemy was near them.

Static- not a physical motion
Raymond is hollering from the swings cause he knows I’m about to do my thing cause the man on the loudspeaker has just announced the fifty-yard dash, although he might just as well be giving a recipe for angel food cake cause you can hardly make out what he’s sayin for the static.

Rowdy-loud and rough
The parkees unfolding chairs and chasing the rowdy kids from Lenox as if they had no right to be there.
The teenagers were being rowdy in the once peaceful park.

Slosh-clumsy
And sometimes after a rain he likes to step down off his tightrope right into the gutter and slosh around getting his shoes and cuffs wet.

Uptight-Being in a tense state
I’ll high-prance down 34th Street like a rodeo pony to keep my knees strong even if it does get my mother uptight so that she walks ahead like she’s not with me, don’t know me, is all by herself on a shopping trip, and I am somebody else’s crazy child.

Glockenspiel- a percussion instrument made of metal bars 
 Most of the kids in my class are carrying bass drums and glockenspiels and flutes.

Prodigy-an unusually talented person
The 6 year old chess prodigy beat everyone at the competition

Corsage- A bouquet of flowers worn on clothing or wrists, like prom.

My friend gave me a corsage to use in prom.

Spiel- a long talk about a subject

Me and my friend had a long spiel about food.

Liable- Likely 

I am more liable to get a pet kitten then my friend because I like cats and she doesn't

Ventriloquist- an entertainer who uses a dummy

The ventriloquist used a dummy to tell a funny story.

Jam packed- full of people

The concert hall was jam packed full of people

Squint- when you close your eyes a bit

When I look up at the sun I have to squint my eyes

Chit chat-simple informal chat

My friend always has a chit chat in middle of the lessons.

Quicksilver- toxic metal

The miners found a lot of quicksilver in the mines last night.

Inferences 

I don’t have much work to do around the house like some girls. My mother does that. And I don’t have to earn my pocket money by hustling; George runs errands for the big boys and sells Christmas cards. And anything else that’s got to get done, my father does. All I have to do in life is mind my brother Raymond, which is enough. 
This tells us that she doesn't have much responsibilities.

“I always win cause I’m the best,”

This tells us that she thinks she's good at running and she doesn't hide it. 

Imagery

I am a little girl with skinny arms and a squeaky voice
This example of imagery uses sight and hearing imagery
We see a little girl with skinny arms and we hear a squeaky voice. 

I think Raymond is a childish person and likes to imagine things.
 he’s subject to fits of fantasy and starts thinking he’s a circus performer and that the curb is a tightrope strung high in the air.
