Hello!
I'm in my 3rd year of learning Mandarin. I have previously (at school/college) studied French (to A level), German and Latin (to O level) and Spanish (basic level).
Mandarin is not that difficult. As a language there are far fewer words - 3000 in regular usage compared with 60,000 in English. There are no tenses and the verb does not decline - in English we would say:
I am
he/she is
they are
but in Chinese the equivalent is
I am
he am
you am
What makes it difficult is two things:
- the tones
You must get the tones right. The tones relate to the vowels, and for each vowel sound there are four different tones. If you get the tone wrong, you will be saying a different word. Thus the word 'ma' could mean mother or horse!
- the characters
If you need to read/write the language then you will have to learn not only the vocabulary but also the characters for them. When you're learning Mandarin you will learn how to read/write the words in pinyin, a sort of romanization of the language, but in China you will have to be able to read the characters.
This is a very good introduction and it comes with a CD so you can make sure you're pronouncing the words properly
Why not see if you can find someone locally who will tutor you?
