Peek or Spy on someone
What word would you use to describe someone deliberately PEEKING at someone else, or spying on them, for instance, peeking at a woman changing her clothes in the changing room. This is for a legitimate purpose. None of the words or phrases I can come up with: echar un vistazo, espiar, seem to capture it. Gracias!
Mirón = peeping Tom (voyeur) por ejemplos;
Unos mirones observerban a los nudistos desde las rocas = A few voyeurs watched the nudists from the rocks
Espiar a algn (alguien) = to spy on someone (like an agent)
Solía espiarlos = he used to spy on them
Fisgón= peeping tom
from the verb fisgonear
