What does the suffix -ad mean?

The suffix "-ad" is not a common English suffix. It is likely you are thinking of "-ad" as part of a larger word, such as "broad-ad" or "broad-band".

* "broad-ad" is a shortened form of "broadcast advertisement," which is a type of advertising that reaches a wide audience.

* "broad-band" refers to a high-speed internet connection that transmits data over a wide range of frequencies.

In these examples, the "ad" part is not a suffix on its own. It comes from the word "advertisement" or "advertising."
