Can you please provide the passage?
English is over 60% Latin and Greek roots, and dictionaries borrow 80% of entries from Latin. In the science vocabulary terms, over 90 percent are derived from Latin. English and French, as well as Spanish, are heavily derived from Latin.
The cost is an expensive habit? not really sure but people who smoke spend a lot of money if they have been smoking for a long time.
I believe true , because the person reading the notes should be able to identify where each note came from.
Hope this helps ^_^
