Iambic pentameter

In poetry, iambic pentameter is a way of rhythmically writing lines of dialogue, poems, or otherwise.
The concept of iambic pentameter is easy to grasp when you know what an iamb is.
An iamb is a two-syllable phrase or word in which the first syllable is unstressed, while the following syllable is stressed.
Here is an example of an iamb. The stressed syllable is in bold lettering.:
I will.
Here is an example of two iambs put together.:
I will go out.
Thus, iambic pentameter is the result of five iambs put together. Here is an example of iambic pentameter.:
The lady in the window looked at me.
Iambic pentameter is quintessential to writing a sonnet. Its most notable usage is in the works of William Shakespeare.
