translate function

I want to do something with translate function, i broke it down to this to ask my question:

select translate('abcdef', 'a', 'A') from dual; returns Abcdef, which is fine

But
select translate('abcdef', 'a', '') from dual; I would think this would return: bcdef but it just returns blank (or null?). Is this correct? Is there a way (or another similar, easy way) to get it to return what I want?
