A person who is learning the alphabet or is in the earliest stages of learning to read and write; a beginner in literacy.
From 'alphabet' + the suffix '-arian' (meaning a person concerned with or devoted to something). The term evolved in the 16th-17th centuries as formal education became more standardized in Europe.
In medieval times, being an 'alphabetarian' was actually a huge achievement—most people never made it past this stage, so 'alphabetarian' could mean you were already one of the literate elite before you could even write your own name.
