Etymology Origin:
The word "primer" traces back to the Latin primus ("first"), reflecting its role as an introductory text or preparatory tool. Originally used in the 14th century for prayer books (the "first" books for learning to read), it later expanded to educational texts and preparatory materials in science and art. The explosive sense derives from the idea of a "first" charge igniting a larger one.
