The Complete Guide for Students on Substitution, Assimilation, Merging, and the Meeting of Two Sokens

I taught the science of morphology in the College of Arabic Language for about thirteen years, a university study that required me to do much research and investigation, and to review what has been written in this art from old and new. I wanted this noble companionship and long experience to have an effect that benefits my students first and people second. And this effect can only be a book that gathers what I aim for in this art, records its roots, and refutes its errors. I do not mean it as a summary, but I want it to be a book from which one can never have enough, and with God's help and success, it will be among the best writings in this science and what has been authored in this art, with clear explanations and easy language; so that both the big and the small can understand it according to their needs without hardship, boredom, or fatigue. Only God is responsible for enabling us to reach what we hope for. I named it: "The Helper of Seekers in Substitution, Deletion, Assimilation, and the Meeting of Two Surnames." I chose for this purpose that its arrangement and method be: an introduction, five chapters, and a conclusion. As for the introduction: it explains the meaning of substitution, deletion, and compensation, their similarities and differences, the types of each, and their general letters. The first chapter: on the substitution of vowel letters to hamza and its reverse. The second chapter: on changing some vowel letters into others, and the remaining types of substitution. The third chapter: on deification by consonantization. The fourth chapter: on deification by deletion. The fifth chapter: on assimilation. The conclusion: on the meeting of two surnames.
