This basic form is reflected in some of the most basic words in the English language: awesome, brave, courageous, excellent. As sentences, however, the word awesome functions best as a modifier: it was awesome to see the alien ship, the home run was awesome. Such sentences are a bit clumsy as poetry, as they violate the basic principle of poetry, already implied in the example above: If a word is used as a modifier of another word, then it usually does not function as an independent sentence, since it cannot stand on its own.
A poem must not be long, but it should be long enough to sustain itself and to bear the weight of meaning which it expresses, and yet not too long to present in the superficial reading of the single sentence of and of each line. A poem may choose to be long or to be brief, but a long poem cannot continue forever.
Poets use the language for artistic ends, though they select particular words in order to carry out their art. In doing so, they are mindful of the words they use. Throughout literature, a few words have gained particular importance for the poet in carrying out his art, and in carrying out their functions in the language, these have become the keys to understanding poetic form. These important words are called the "figures of speech". In general, figures of speech are metaphors, metonyms, synecdoches, and other devices in which a word is used to convey a sound, image, or series of images that would be beyond what the language can naturally express.
These figures of speech are not a fixed part of the English language; many words that have often been used in place of others or as a synonym for their root, and even entire words that can be used in such a way are being replaced by more recently created words. d2c66b5586
