Angelus curator --> Custos angelus or Angelus tutelaris

But are you sure it is in nominative here? Shouldn't be vocative?

"Anima mea cave".

Hehehe! "CAVE CANEM" = AVOID A DOG! (Literally: Beware of the dog )
So, unfortunately it is not a good word, dear Goncin. I propose: "protege" or "defende", "custode" + ACCUSATIVUS.

Aneta,

According to this dictionary, "caveo" + dat. means to take care of.

But I'll edit it.

But you didn't put "anima mea' in dative, sorry...

It can be of course: 'Animae meae cave'
but the others verbs are better in religious context...

Once more I just confused ablative with dative (which use to be the same, but not in 1st declension...)

Ok. It happens. Don't worry.

But you didn't answer my question above:

"But are you sure it is in nominative here? Shouldn't be vocative?"

I meant the words:
Custos angelus, socius meus

Edited. Hope its all right now.

Custos angele, mi soci/comes.

I was dealing with 'angelus' as a 4th declension noun. Fixed.
