Pronunciation: [ɐ tə zˈɛd] (IPA) 
The phrase "A to Z" refers to something that covers the full range or scope, from beginning to end. In IPA phonetics, it is transcribed as "eɪ tə ziː", where the "eɪ" sound is equivalent to the letter "A", the "tə" sound is the schwa sound often heard in unstressed syllables, and "ziː" represents the letter "Z". The spelling of this phrase reflects the order of the English alphabet, with the letter "A" coming before the letter "Z".
"A to Z" is an idiomatic expression used to describe something that encompasses or covers the entire range or breadth of a particular subject or topic, typically in a sequential or comprehensive manner. It refers to including every possible element or aspect, from the beginning to the end or from the first to the last item, in a systematic or exhaustive manner.
This expression is derived from the English alphabet, where "A" represents the first letter and "Z" represents the last letter. Therefore, when something is said to be "A to Z," it means it includes everything from the very beginning to the absolute end, without any omissions or exclusions.
The phrase is frequently employed in various contexts, such as when discussing a complete guide or comprehensive overview of a subject. For instance, a book claiming to provide an "A to Z guide on gardening" would imply that it covers all aspects of gardening, starting from the basics to the most advanced techniques, without omitting any relevant topics in between.
Furthermore, this expression is often used figuratively to emphasize the thoroughness, completeness, or inclusivity of a particular undertaking. For instance, a person may say they are responsible for managing a project from "A to Z" to convey that they are involved in every stage, from the initial planning to the final execution.
