This monosyllable, lurking in the undergrowth of grammatical complexity, can be the bane of Spanish learners’ lives. Why?

But, let’s keep it simple. There is a ton of resources on the net that pick through this grammatical minefield, if you need it. http://spanish.about.com/cs/grammar/a/porpara.htm is as good place to start.
Examples of use:-
