We'll have to "keep an eye" on him

Question

Tendremos que vigilarlo. Is that right? Gracias.

Answer 1

Sí, tendremos que vigilarlo.

Answer 2

"Vigilarlo" is fine if you suspect that this person is likely to do something bad as soon as you look away, or if you can't keep your eyes off for a second because something could happen to that baby.

Otherwise, I'd say "echarle una mirada/un ojo a alguien", if you are just going to keep an eye from time to time (see Gekkosan's suggestions too), or "cuidar a alguien" if you are taking care of that person.

Answer 3

Vigilarlo is correct. However, there's a direct equivalent to the idiom in Spanish:

"Hay que ponerle un ojo encima". "¡No le quites el ojo de encima!"

Here you hear "ponerle un ojo" a lot...same meaning just shortened. ;o) - cristalino, Feb 7, 2011
