Seeing as you ask, here’s the poem I was taught in primary school to remember, er, word stuff.
Every name is called a NOUN, field and fountain, street and town
In place of noun the PRONOUN stands, like he and she can clap their hands
The VERB means action, something done – To read, to write, to jump, to run;
How things are done, the ADVERBS tell, As quickly, slowly, badly, well;
The PREPOSITION shows relation, As in the street, or at the station;
CONJUNCTIONS join, in many ways, Sentences, words, or phrase and phrase;
The INTERJECTION cries out, ‘Hark! I need an exclamation mark!‘
