una sombra!

Question

De que se trata "una sombra" en esta frase? adaptó los modales de su antiguo profesor que hacia catorce años que era una sombra.. muchas gracias!

Answer 1

My guess is that he was a learning follower of his old teacher for 14 years. Una sombra or 'a shadow' seems like the person follows close enough to be in his shadow but sees himself in a lower learning position to the teacher.
