In English, a native speaker learns to spell based on the way words sound. Correspondingly, one learns to pronounce a word based on its spelling, using phonetics. This involves rules learned when quite young, such as "I before E, except after C, or when sounded as A, as in neighbour or weigh." and the like. Most rules are simply absorbed as we grow up and obtain more vocabulary.
However, when learning another language, particularly as an adult, it can be more difficult to pick up these "rules" and it helps if they are explicitly stated somewhere. For example, in my Italian lessons, I have learned a couple, such as the "soft" G or C when followed by I (eg: Giacomo or città).
There must be many other grammatical rules such as these English and Italian examples. Does anyone know of such a list of rules for Italian, but in English so a beginner can understand?
