"By all means" grants permission. Example: "May I drive?" "By all means" (that means yes.) "By no means" means "Not at all; certainly not." Example: "May I drive?" "By no means." (that means no.) "By any means" follows a negative and means "in any way; at all." For example, "I am not an expert driver by any means" (This means "I am NOT an expert driver at all") "By means of" means "with the help of." Example: "Supplies arrive at the stores by means of a truck." That means with the help of a truck, the supplies arrive at the stores. I hope this helps!!

Here are some examples: "You can go to see the football match, by all means, but don't expect any dinner when you get home."

"He went to the match by various means of transport"
