What is the meaning of the suffix "-gram"?

The suffix "-gram" is derived from the Greek word "gramma," meaning "something written" or "a letter." In medical and scientific terminology, it typically refers to a record or a written representation of data. This can be seen in various terms such as "electrocardiogram," which is a written record of the heart's electrical activity, or "radiogram," which refers to an image produced by X-rays.

The other options relate to different suffixes or roots that convey distinct meanings. For instance, the suffix indicating "stopping" does not connect to "-gram," nor does any suffix meaning "swallowing" or "falling." Each of those options represents an entirely different concept unrelated to the idea of recording information. This distinction underscores why the recognition of "-gram" as meaning "record" is fundamental in medical and scientific contexts.
