rosetta stone turkish...
rosetta stone was great for building vocabulary and comprehension. but as other reviewers have said, a book explaining turkish grammar is essential to have in addition to rosetta stone. because rosetta stone is an incomplete turkish course, $200 is a bit pricy, but if you have some spare money, it makes getting familiar with the turkish language and building vocabulary worlds easier. books are tedious and hard to remember, but the audio and visual parts of rosetta stone help so much, and the sound quality and rate of speech (not too fast) is excellent. after reviewing a few chapters in 'teach yourself turkish', for example, i review some sections of rosetta stone, applying the grammar i learned from the book, and the grammar sticks in my head MUCH better. in sum, if it wont hurt your wallet too much, rosetta stone is a recommended supplement to turkish language books.
