The prefix 'de-' in medical language indicates a lack of or removal of something. This prefix is derived from Latin, where it often suggests a reversal or negation of a condition. For instance, when used in medical terms, it can imply a decrease or loss, as in the term "dehydration," which refers to a lack of water in the body. This highlights that 'de-' signifies the absence or reduction of a specific substance or condition.

While the other options highlight different concepts, they don't align with the specific meaning of the prefix 'de-.' Options such as addition or excess refer to an increase or presence of something, which is opposite to what 'de-' conveys. The concept of absorption also does not align with the prefix's indication of lack or removal. Therefore, the correct understanding of the prefix is crucial for the interpretation of medical terminology.
