Over the past seven years, I have dedicated thousands of hours to researching transition words and phrases in both English and Persian. This extensive effort has culminated in the creation of comprehensive reference books for each language. Each book contains over 10,000 entries meticulously organized into 25 chapters. These entries are further categorized into hundreds of subcategories across 1,200 pages, providing a thorough resource for grasping the meanings, synonyms, and usages of transition words and phrases in contemporary language. Having completed separate reference books on transition words in English and Persian, my current project is to create bilingual versions, aiming to enhance accessibility for Persian-speaking English learners and English-speaking Persian learners worldwide.
