fourth-year

the compound 'fourth-year' is a modern english formation built from two fundamental germanic elements. 'fourth' derives from the old english 'feorþa', the ordinal successor to 'fēower' (four), which traces back to the proto-indo-european root kʷetwer-. 'year' originates from old english 'gēar', related to proto-germanic jērą, and ultimately to the pie root yeh₁r- meaning 'year' or 'season'. the logic of the compound is transparently numerical and temporal, directly combining the concept of the fourth in a sequence with a standard unit of academic or chronological time to specify a particular stage within a multi-year program.

Structure: fourth (ordinal number) + year (time period) 'fourth' (from old english 'feorþa', ordinal form of 'four', of germanic origin); 'year' (from old english 'gēar', of germanic origin, meaning a period of time comprising a cycle of seasons).
