In some situations I know that short prepositions have to have an "o" on the end of them, for example:
Я живу во Англии
Моя мать говорит с братом обо мне
Они едут ко мне
It seems that the most common consonant cluster this occurs with is those words beginning with "мн", like "обо мне", "со мной" etc... but as in the first example, if that's right, then there must be other clusters it occurs with. Can anyone point those out to me please, either through examples or through a site link?
Спасибо большое
