yes..you're right. You look a word up in the dictionary or look up a word. You look for a new job in the newspaper for example. You look for your car if it's lost or maybe collect it or pick it up if it's at the garage being repaired. You meet a friend if you've already decided to meet or call for a friend if you go to his/her house and you are a young person probably a child."let's go and call for Maria" Another one is to pick your son/daughter up at school at the end of the day. So it really depends what you are 'buscando' and whether it's lost or not.

Hi Kulia Both mean exactly the same and both are interchangeable.Perhaps 'reservation' sounds 'posher' , maybe used more in American but it depends on the individual.I would generally say 'booking' but not because it's any more correct. Gramatically.....a booking/reservation ? as it's singular but any booking/reservation? would be used too.

I'm sorry.I wish I could help you but without looking further I don't know what it means in relation to paypal.Obviously I know what a mover and shaker are but not in this context.Sorry.Hope somebody else can help you.

They are both gramatically correct. However,in the first sentence we don't know whether it will or won't happen as 'might' means 'possibly' whereas in the second sentence it will definately happen so they are slightly different sentences.

If you're wondering what preposition to use it's 'of '...How can I inform my friends of my new number?
