Etymology
the word 'eastbound' is a modern english compound formed from two distinct linguistic elements. the first element, 'east', originates from the old english 'ēast', a term of germanic lineage that fundamentally refers to the direction of the rising sun. the second element, 'bound', has a more complex journey, deriving from the old norse 'búinn', meaning 'prepared' or 'destined', which evolved in middle english to signify heading for a particular destination. when combined, these morphemes create a transparent and logical meaning: 'destined or heading towards the east', a term commonly used in transportation and navigation contexts to describe direction of travel.
Analysis
east: from old english 'ēast', of germanic origin; related to dutch 'oost' and german 'ost', denoting the direction of the sunrise. bound: from middle english 'boun', from old norse 'búinn', past participle of 'búa' meaning 'to get ready, dwell'; the sense 'going towards' developed from the meaning 'destined'.
