comma or 'and' with adjective [conjunction]: a soft, honest straight

[as_99]

I would like to know when we put a comma "," between two adjectives and when put "and".

See the following example:

" ... to adopt a soft, honest straight campaign."

they put a comma rather than "and" !

The general rule is to put a comma before each item in the list, except for the last one. Before the last item, you can put either "and" or comma + "and" (although the first way might be more common).

To take your example:

...to adopt a soft, honest, straight campaign.

or

...to adopt a soft, honest and straight campaign.
