The language of poetry has the characteristics of being distinct from the other forms of literature. A poet, in order to make his poem impressive, selects words which besides determining the semantic structure of a poem show a special and grand unity of sound structure. i.e., the appreciation of a poem meaning comes from the choice of special phonemes through the choice of special words. The objectives of this paper are to: 1- Study the relationship between sound and sense in lyric or narrative poetry.  A poem by Alkhansaa (the most famous Arabic poetess) will be selected for studying. 2- Apply the approach of  Dell Hymes to prove the phenomena.
