The poet is very careful in choosing words because the written words must be taken into account their meaning, the sound composition in rhyme and rhythm, the position of the word in the middle of the other word context, and the word position in the whole poem. Therefore, in addition to choosing the right word, the poet also considers the word order and the magical power or power of the words. Words are given new meaning and meaningless meaning given according to the poet's will. Because of the importance of words in poetry, the sound of words is also carefully considered in the election. Since the choice of words takes into account the various aesthetic aspects, the words the poet has chosen for his poetry are absolute and can not be replaced with the words he says, even if their meaning is no different. Even if the element sounds almost identical and the meaning is the same, the selected word can not be changed. If the word is replaced it will interfere with the composition with other words in the overall construction of the poem.
In the poems 'Patience' by Chairil Anwar diction or word selection using words that are easily understood by the reader even in the structure of the word irregular and less in accordance with the structure of the word in general. For example: the word 'nggonggong' in the word structure is generally not 'barking' but 'barking', but the poet prefers the word nggonggong as a word that has an original or atarivate symbol to produce poetic power.
