make-up
 

Hello! I'm looking for the direct translation of the word make-up as in "I have to make-up an assignment that was due yesterday". If anyone out there knows please thank you for sharing.

Re: make-up
 

makeup:
an event that is substituted for a previously cancelled event; "he missed the test and had to take a makeup"; "the two teams played a makeup one week later"
Try with "aplazar". It's more like to postpone
"Tuve que aplazar un encargo que tenía para ayer"
others
postergar, retrasar, demorar, diferir, posponer
"Tuve que retrasar un encargo que tenía para ayer"
"Tuve que postergar un encargo que tenía para ayer"
"Los dos equipos jugaron el partido aplazado una semana después"
"Los dos equipos postergaron el encuentro una semana"
"Los dos equipos jugaron una semana después el partido pospuesto"

Re: make-up
 

"To make up" has quite a few different meanings, but in the sense that you're asking, I'd say the best translations would be:
reponer, compensar, completar, entregar o simplemente hacer.

I have to make-up an assignment that was due yesterday.
Tengo que completar una tarea que tenía que entregar ayer. <= I have to finish the assignment
Tengo que hacer una tarea que debía entregar ayer. <= I have to make up the assignment
Tengo que volver a hacer una tarea que debía entregar ayer. <= I have to redo/rewrite the assignment

Does that help?
