What is defined by the suffix "-cele"?

The suffix "-cele" refers to a protrusion or swelling that often occurs due to a herniation of tissue. In medical terminology, it typically describes an abnormal pouch that forms in an organ or tissue, indicating that something has pushed out from its normal location. An example of this can be seen in terms like "hernia," where a part of the body pushes through a weak area, or "cystocele," which refers to a protrusion of the bladder into the vaginal wall.

The other options do not align with the definition of "-cele." "Pertaining to" is generally indicated by different suffixes like "-al" or "-ic." The action "to kill" is denoted by the suffix "-cide," found in terms like "suicide." "Hearing" is associated with the suffix "-acous" or "-audio," which relates to auditory functions. Thus, the definition of "-cele" as a protrusion is the one that accurately captures its medical context.
