The subject may follow the verb in Spanish. This is especially the case when asking questions. Have a look at the following examples:

María come. = Mary is eating. -or- Mary eats. (Marie mange.)
¿Come María? = Is Mary eating? -or- Does Mary eat? (Marie mange-t-elle?)
¿Qué come María? = What is Mary eating? -or- What does Mary eat? (Qu'est-ce que Marie mange?)
María come el queso. = Mary is eating cheese. -or- Mary eats cheese. (Marie mange du fromage.)
¿Come el queso María? = Is Mary eating cheese? -or- Does Mary eat cheese? (Est-ce-que Marie mange du fromage?)

It seems to me that you can say the subject first in an interrogative if you want to emphasize it, but the usual order is verb first, then subject.

ok now i understand .Pero if you could help me on one last thing i would be very thankful to you - while most of the time the person is before the verb : " trago mi saliva " i saw sentence constructions like this : "Serviría de guía un brasileño de nombre Sergio" where the verb is before the rest ,such a syntax does not really exist in French and so i have a bit of difficulty in grasping it :this type of construction is an alternative one or has it to be used in some particular cases ? i would also willingly accept anything you can tell me about such a construction. Thanks in advance Rusty (as yes your answers are realli helpful )

In my response, I said that the prepositions 'a' or 'de' did not change the meaning of the verb. The other verbs you mentioned (go out; look up; go around) are phrasal verbs. These are used a lot in English. Some Spanish verbs change meaning when followed by specific prepositions, but a good dictionary will alert you that fact. 'Lograr' doesn't need a preposition to convey its meanings (there is more than one meaning).

Hope this helps.

hiii ; thank you very much for your response ;but there just a small thing : i know that lograr is not a 'verbe a particule' like you you have in english : go out ; look up ;go around etc... but when it does being followed by "a" or "de" ; does it gives off another meaning ? thanks
