What does the word immo really mean and how can I use it? I read this and this dictionary entry, and I was left confused. Some of the uses I can understand, but some I cannot. Either I do not have enough context to see what immo does or I cannot parse the English. For example, the translation "nay verily" (see first link above) does not reduce my confusion at all.
Could someone provide me with a list of possible uses of immo with simple examples? I would prefer simplified examples focusing on how immo works and interacts with other words, without too many distractions. Linking the different uses to the dictionary entries would also help me decipher the dictionaries. Is there perhaps a good rule of thumb for interpreting immo?
I was reminded of this problem by this question about "yes" and "no" — and in particular brianpck's comment under the answer.
