About 80 percent of the entries in any English dictionary are  borrowed, mainly from Latin.   Over 60 percent of all English words have  Greek or Latin roots.  In the vocabulary of the sciences and  technology, the figure rises to over 90 percent.  About 10 percent of  the Latin vocabulary has found its way directly into English without an  intermediary (usually French).  For a time the whole Latin lexicon  became potentially English and many words were coined on the basis of  Latin precedent.  Words of Greek origin have generally entered English  in one of three ways: 1) indirectly by way of Latin, 2) borrowed  directly from Greek writers, or 3) especially in the case of scientific  terms, formed in modern times by combining Greek elements in new ways.   The direct influence of the classical languages began with the  Renaissance and has continued ever since. Even today, Latin and Greek  roots are the chief source for English words in science and technology.
So this is great for Italian students of English because right at the start they already know almost 80% of the entire English vocabulary (wink wink!). So then why is it that when they speaking with English speakers they understand almost nothing and are totally not understood?
That is because the English pronunciation of Latin words arecompletely different from the Italian. Take the example of psychology pronounced as /saɪˈkɒl ə
ə dʒi/ (http://dictionary.reference.com/browse/psychology) rather than /'psɪkol
dʒi/ (http://dictionary.reference.com/browse/psychology) rather than /'psɪkol o
o 'dʒia/ as in Italian. So when a student who doesn't know the correct pronunciation of the English word hears it from a native speaker   will not recognize it although he knows the word perfectly well from his/her own language.
