Some common nouns in English like information are uncount nouns even though they have plurals in other languages:
Let me give you some advice.
How much luggage have you got?
If we want to make these things countable, we use expressions like:
a piece of ...
pieces of ...
a bit of ...
bits of ...
an item of ...
items of ...
Let me give you
a piece of advice.
That's
a useful
piece of equipment.
We bought
a few bits of furniture for the new apartment.
She had six separate
items of luggage.
However, accommodation, money and traffic cannot be made countable in this way. We need to use other expressions:
I've lived in three apartments. ✔
bits of accommodation ✖
Smith received three large sums of money. ✔
pieces of money ✖
We got stuck in two traffic jams. ✔
pieces of traffic ✖
