from Act One Scene 5 of Romeo and Juliet

The Shakespearean sonnet is divided into three quatrains and a couplet rhymed abab cdcd efef gg. The couplet provides an epigrammatic comment on the narrative or problem put forth in the quatrains. (from Thomson-Gale Literary Glossary):

In addition, sonnets are written in iambic pentameter, meaning that there are 10 syllables per line, and that every other syllable is naturally accented.

ROMEO
If I profane with my unworthiest hand	a
This holy shrine, the gentle fine is this:	b
My lips, two blushing pilgrims, ready stand	a
To smooth that rough touch with a tender kiss.	b
JULIET
Good pilgrim, you do wrong your hand too much,	c
Which mannerly devotion shows in this;	d
For saints have hands that pilgrims' hands do touch,	c
And palm to palm is holy palmers' kiss.	d
ROMEO
Have not saints lips, and holy palmers too?	e
JULIET
Ay, pilgrim, lips that they must use in prayer.	f
ROMEO
O, then, dear saint, let lips do what hands do;	e
They pray, grant thou, lest faith turn to despair.	f
JULIET
Saints do not move, though grant for prayers' sake.	g
ROMEO
Then move not, while my prayer's effect I take.	g
Thus from my lips, by yours, my sin is purged.	h
JULIET
Then have my lips the sin that they have took.	i
ROMEO
Sin from thy lips? O trespass sweetly urged!	h
Give me my sin again.
JULIET
You kiss by the book.	i
