A NOUN’s the name of anything;
As school or garden, hoop or swing.
ADJECTIVES tell the kind of noun:
As great, small, pretty, white or brown.
Instead of nouns the PRONOUNS stand
Her face, his face, our arms, your hand.
VERBS tell of something being done;
To read, count, sing, laugh, jump or run.
How things are done the ADVERBS tell;
As slowly, quickly, ill or 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!

A Google search reveals that the poem is titled 'A Grammar Rhyme' and the authors (!) are by David B Tower and Benjamin F Tweed.
