Etymology
the word 'junior' entered english in the late 13th century, directly from the latin word 'iūnior', which is the comparative form of 'iuvenis', meaning 'young'. the latin 'iuvenis' itself descends from the proto-indo-european root h₂yuh₁en-, meaning 'young, youthful'. the comparative suffix '-ior' in latin denotes 'more', thus 'iūnior' literally meant 'younger'. this comparative sense was retained as the word was adopted into english, initially used to denote a younger person, especially a son named after his father. over time, its application broadened beyond familial contexts to signify lower rank or standing in any hierarchical system, such as in professions or education, while still retaining its core association with relative youth.
Analysis
the word 'junior' is a simplex loanword from latin. it is not productively formed from smaller, independently meaningful morphemes in modern english spelling.
