The textbook I'm reading now has liberal sprinklings of the 儿 character suffixing words that I have not previously seen suffixed.
For example: 空儿。
How should this be pronounced? Are there any rules of thumb for pronouncing the 'er' in cases where the previous character doesn't end in a vowel? (Another example would be 馆儿 although I already know that sounds like 'guer')
In my experience, sometimes people in the south will switch the 儿 for a 子, for example "lens cap" is 镜头盖 but in the north will be shortened to "盖儿" and in the south "盖子"
