Read good poetry and read it well, tracing the countless incarnations of every word. These are after all the same words lying dead in dictionaries or leading a gray life in speech. Then why do they shine like new in poems, as if the poet had just discovered them?

He who repeats a tale after a man,
Is bound to say, as nearly as he can,
Each single word, if he remembers it,
However rudely spoken or unfit,
Or else the tale he tells will be untrue,
The things invented and the phrases new.

The poet, in the novelty of his images, is always the origin of language.

Poetry remakes and prolongs language; every poetic language begins by being a secret language, that is, the creation of a personal universe, of a completely closed world. The purest poetic act seems to re-create language from an inner experience that … reveals the essence of things.

The poet, by composing poems, uses a language that is neither dead nor living, that few people speak, and few people understand … We are the servants of an unknown force that lives within us, manipulates us, and dictates this language to us.

Trying to use words, and every attempt
Is a wholly new start, and a different kind of failure
Because one has only learnt to get the better of words
For the thing one no longer has to say, or the way in which
One is no longer disposed to say it. And so each venture
Is a new beginning, a raid on the inarticulate
With shabby equipment always deteriorating
In the general mess of imprecision of feeling,

No writer ever knows enough words but he doesn’t have to try to use all that he does know. Tests would show that I had an enormous vocabulary and through the years it must have grown, but I never had a desire to display it in the way that John Updike or William Buckley or William Safire do to such lovely and often surprising effect. They use words with such spectacular results; I try, not always successfully, to follow the pattern of Ernest Hemingway who achieved a striking style with short familiar words. I want to avoid calling attention to mine, judging them to be most effective as ancillaries to a sentence with a strong syntax.
My approach has been more like that of Somerset Maugham, who late in life confessed that when he first thought of becoming a writer he started a small notebook in which he jotted down words that seemed unusually beautiful or exotic, such as chalcedony, for as a novice he believed that good writing consisted of liberally sprinkling his text with such words. But years later, when he was a successful writer, he chanced to review his list and found that he had never used even one of his beautiful collection. Good writing, for most of us, consists of trying to use ordinary words to achieve extraordinary results.
I struggle to find the right word and keep always at hand the largest dictionary my workspace can hold, and I do believe I consult it at least six or seven times each working day, for English is a language that can never be mastered.* [*Even though I have studied English for decades I am constantly surprised to find new definitions I have not known: ‘panoply’ meaning ‘a full set of armor’, ‘calendar’ meaning ‘a printed index to a jumbled group of related manuscripts or papers’. — Chapter IX “Intellectual Equipment”, page 306

This poetry. I never know what I'm going to say.

...poetry cannot speak without remembering the turns of the sun and moon, and the rhythm of the ocean, and the recurrence of human generations, the returning waves of life and death.

The nice thing about poetry is that you’re always stretching the definitions of words. Lawyers and scientists and scholars of one sort or another try to restrict the definitions, hoping that they can prevent people from fooling each other. But that doesn’t stop people from lying.

Cezanne painted a red barn by painting it ten shades of color: purple to yellow. And he got a red barn. Similarly, a poet will describe things many different ways, circling around it, to get to the truth.

My father also had a nice little simile. He said, “The truth is a rabbit in a bramble patch. And you can’t lay your hand on it. All you do is circle around and point, and say, ‘It’s in there somewhere.

There is the buried language and there is the individual vocabulary, and the process of poetry is one of excavation and of self-discovery. Tonally the individual voice is a dialect; it shapes its own accent, its own vocabulary and melody in defiance of an imperial concept of language, the language of Ozymandias, libraries and dictionaries, law courts and critics, and churches, universities, political dogma, the diction of institutions. Poetry is an island that breaks away from the main.

Yes, I repeat, there is always something to be done with words, and here are thirty-two authentic words from the Master Philologist himself, not to speak of three commas and a full-stop. Oh, I shall certainly go far with this.

A poet can survive everything but a misprint.

The poet thinks with his poem...
