Here is a sonnet, written in iambic pentameter, about violence.
Iambic pentameter means that there are ten syllables every line. Each grouping of two syllables is called an “iamb”. A sonnet uses the rhyme scheme abab cdcd efef gg. Each letter represents a line of the poem, and the same letter means that those two lines rhyme.
To steal a life use words of hate, or throw
Insults degrading. Earth so green now red
With blood of men from which insults free flow.
The violence feeds the stomach of hate bread.
The sports of now are harmful games to play.
Hits vicious, injuries are of no lack.
The blood of players falling towards day,
An astronaut to orbit coming back.
An accident or not, the violence found
On Earth is harming people young and old.
It will keep progressing on with no sound.
A speaker without power, endless cold.
Violence is much too harsh, and too widespread.
If cease it does not, Earth so green turns red.
