Simple as A-B-C

Origin

The phrase draws its compelling power from the absolute foundational nature of the alphabet itself. For centuries, learning the A-B-C has been the very first, most fundamental step in education, the gateway to literacy and knowledge. Before one can read a single word or write a coherent sentence, the individual letters must be mastered. This universal and undeniable truth about learning, cemented in the minds of generations, transformed the simple act of reciting the alphabet into a powerful metaphor for anything utterly straightforward, requiring minimal effort or intellect to grasp.
