The works of Hakim Tirmidhi contain very interesting information on lexicology. In an environment where sciences are considered as a whole, Tirmidhi strives to get to the deep meaning of every word. To do this, he connects Arabic word formation with the internal meaning of the word, distinguishes between original and non-original words, and draws conclusions that letters carry a semantic load in the word. He also claims that there are no synonyms in the Qur'an and that every word is unique, even if it has a similar meaning.
