Some of the hidden semantic and rhetorical delicacy Of didactic type in Saadi's words

Although some of Boostan and Golestans poems and phrases have simple appearances، others have Semantic complexity. At first glance we can’t understand the depth of meaning even with relying on rhetoric knowledge. Saadi has made deep semantic structures with the help of complex network of words which sometimes strengthen by using the figure of speeches. Saadi has used hidden meaning in his works because he was a proficient in Persian language، had had knowledge about other sciences، had gained experiences form his travels and had known the different culture. Above all، Saadi’s accuracy and effort for making an educational and instructive work has appeared both on surface and deep of couplets which sometimes was ignored by his exponents. The purpose of the present paper، therefore is to interpret and explain some of phrases and poetry that their meanings were hidden for previous exponents.
