In casual, spoken English, there are certain "filler-words" which are very common, but don't really add much to the actual meaning of the sentence. For example: "like, you know..., look....".
The same thing seems to exist in Italian. I want to a) confirm that this true, b) find out what the common filler-words are.
For example, are these common filler-words?:
- guarda (look)
- dai (come on now)
- sai (you know)
What other Italian words or expressions would be in this category?
