What is the opposite of free as in "free of charge" (when we speak about prices)? We can add not for negation, but I am looking for a single word.
Free entrance X chargeable entrance. Free parking X paid parking. Free service X chargeable service. Free consultation X paid consultation. Free health care X expensive health care. Free toilet X pay toilet. Free fare (in the sense of a free ticket to travel, the opposite can be a paid ticket). Here there is a mentioning of paying a ticket fare.
