Prefixes

A prefix is a group of letters that precedes a word and changes the meaning of that word. In English the prefixes work in a similar way to Castilian. They are placed before a word and modify its meaning, but they do not function independently. In general, they come from ancient Latin or Greek prepositions, so you will easily recognize them.
