Thanks everyone for your help. I have enjoyed the book 'Let's Learn Hiragana' but it is a shame it has been a bit thin on the ground in explanations. It is purely a book to help in writing.
So, let me get this right ん always comes after a vowlel no matter if 'ne/na/no/nu/ni' directly follows the vowel? Okay.
However, the example in my book gave me ta n'i (unit) ta ni (valley). I've tried looking this up in my dictionary but no luck. What does the ' stand for? Is it the 'n' you mentioned Nick in your example? So it always implies a repetition of the consonant or vowel? This would mean unit = tanni. Sorry to mither about this, but I really feel I can't move onto Katakana feeling unsure in these problems.
Can anyone help me on the double 'o' problem I encountered? How do I know when the second 'o' is う or when it is お - both of these are possible according to my book. (Examples of words given are ookami, ookii, kyoo, doozo - is this a pronunication thing Bucko?)
My other problem was double consonants. I was fine in the majority and then I had to transform 'atachi' (over there). Sorry for sounding stupid on this, and on all other points, but am I supposed to ignore the 'c'?
Ah well,
Thanks again for all of your help but any further explanations would be much appreciated
