@desertrose,
Quote:Can anybody tell me why we say "pay by credit card" instead of "pay by A credit card" ? Why we say that without "a" article? Thanks a lot!
We say it that way because it describes a
general manner of payment; pay by check/credit card/debit card.
A specific reference to such a payment would see the preposition changed to 'with',
pay with a credit card/with cash/with a debit card/pay with a check
