The term "primer" has appeared in a range of literary contexts, functioning both as an introductory text and as an ordinal marker. In works like those from "A First Spanish Reader," it is used in its traditional sense of “first” or “initial”—as in queries about the first ship passing through a canal ([1], [2], [3]), or describing the location of the first floor in Spain ([2], [4], [5]). In contrast, English-language texts often invoke "primer" as a basic instructional book essential to early learning, as seen in Helen Keller’s narratives about reading and exploring words ([6], [7], [8]) and in Louisa May Alcott’s call to “bring out your primer” to begin an activity ([9], [10]). Additionally, authors like Walt Whitman and Mark Twain explore its metaphorical or nuanced connotations—Whitman alluding to the refined quality of a long-primer of type ([11]) and Twain employing the term to suggest both a beginning and a quality of experience ([12], [13]). Thus, across different literary traditions, "primer" encapsulates both a literal tool for instruction and a symbolic representation of beginnings or primacy ([14], [15], [16]).
