Three little words you often see
Are ARTICLES: a, an, and the.
A NOUN's the name of anything,
As: school or garden, toy, or swing.
ADJECTIVES tell the kind of noun,
As: great, small, pretty, white, or brown.
VERBS tell of something being done:
To read, write, count, sing, jump, or run.
How things are done the ADVERBS tell,
As: slowly, quickly, badly, well.
CONJUNCTIONS join the words together,
As: men and women, wind or weather.
The PREPOSITION stands before
A noun as: in or through a door.
The INTERJECTION shows surprise
As: Oh, how pretty! Ah! how wise!
The whole are called the PARTS of SPEECH,
Which reading, writing, speaking teach.
