Let's diagram a sentence together.
(Victor Hugo)

Let's diagram a Victor Hugo quotation together. 

"To learn to read is to light a fire; every syllable that is spelled out is a spark."

To learn to read is to light a fire; every syllable that is spelled out is a spark = sentence 

To learn to read is to light a fire = independent clause 

To learn to read = subject, infinitive phrase

to read = direct object of to learn, infinitive

is = linking verb

to light a fire = predicate noun, infinitive

fire = direct object of to light

Here I am next to Victor Hugo's desk. Notice the height of the desk; he liked to write while standing up. 

every syllable that is spelled out is a spark = independent clause (includes a dependent adjective clause)

syllable = subject, noun

is = linking verb

spark = predicate noun

every = adjective 

that is spelled out = dependent adjective clause

that = relative pronoun & subject of adjective clause

is spelled out = verb phrase

is = helping verb

spelled out = main verb, intransitive complete passive phrasal verb

If you've already learned a bit about diagramming, you might be feeling bold enough to try diagramming sentences yourself. Here are three more quotations from Victor Hugo. Try diagramming them with a pen and paper or with the free Let's Diagram site. Answers are just below this section. Have fun! 

1. Idleness is the heaviest of all oppressions.

2. A man is not idle because he is absorbed in thought. 

3. Laughter is the sun that drives winter from the human face.
