輩 older or younger colleague

Is the guy writing this already an old fart? HAI.

It is injustice that my older classmates get to drive the car, but us sophomores don't!

Person ahead of you at school ★★★☆☆ CCW
先 (earlier/ the tip) + 輩 (older or younger colleague) = 先輩 (Person ahead of you at school)

Usually translated as "person ahead of you in school．"　(opp.後輩 (こうはい））. But the 先輩・後輩 system of unchanging, rigid heirarchy is in full effect all throughout Japanese society, from the punk scene to corporations and everywhere in between. People still call each other 先輩 40 years after they graduate.

someone younger than you in school ★★☆☆☆
後 (afterwards / behind) + 輩 (older or younger colleague) = 後輩 (someone younger than you in school)

old person. ★☆☆☆☆
年 (year) + 輩 (older or younger colleague) = 年輩 (old person.)
