Alright, this might sound stupid but I've been wanting to ask this for a while.
Sometimes simultaneously pronouncing each word separately and quickly is bloody difficult (or rather, weird), so I was wondering if it's ok to combine some of the words. For example,
Can I pronounce В это as вэто?
I'm asking only because, usually I do make a quick pause when pronouncing this kind of sentence and I'm not sure whether that's good or bad.
