There’s a lot of confusion around the difference between resorption and reabsorption. They sound very similar, and refer to similar things, so even experienced writers often mix them up.
So what exactly is the difference between these two words?
The short answer is that reabsorption refers to the process of absorbing something again, while resorption refers to the process of losing substance.
In this article, we’ll help you remember the difference between resorption and reabsorption and show you examples of each word in context.
What’s the Difference Between Resorption vs. Reabsorption?
Let’s start with a basic definition of each word.
Reabsorption Meaning
The noun reabsorption refers to the process of absorbing again. It comes from the prefix “re-” and the noun “absorption.”
Reabsorption is most often used in medicine to describe the process of something being absorbed repeatedly.
For example, if you absorb a substance, secrete it back out, and then absorb it again, the subsequent absorption is called reabsorption.
In renal physiology, tubular reabsorption is a major step in urine formation. This term describes the process by which solutes and water are removed from tubular fluid and put back into circulating blood. This process is called tubular reabsorption because these substances in the tubular fluid have already been absorbed once in the intestines.
Politically, the word reabsorption often refers to a reunification between different countries or territories that used to be a single entity. For example, if an empire dissolves and then re-forms, you could say that the empire has reabsorbed its old territory.
Resorption Meaning
The noun resorption is often used to refer to the process of losing substance, due to that substance being absorbed by something else.
This word is most often used in medicine to describe the loss of tissue or bone. For example, bone resorption is a health condition that weakens bones.
Essentially, the bone resorption process takes place when bone tissue is absorbed by circulating blood.
Another medical term is fetal resorption, also known as “vanishing twin.” This occurs when one twin in the uterus absorbs the other, meaning that only one baby is carried to term.
In geology, resorption refers to the redissolving of crystals into the molten magma of an igneous rock. These crystals are lost when they are absorbed by the molten magma.
Notice that all these examples of resorption involve absorption, just like reabsorption, but in these cases the process of absorption results in a loss.
We use the word resorption, not absorption,when talking about losing substance.

Conclusion on Resorption vs. Reabsorption
In general, resorption is used to describe the process of losing substance, while reabsorption refers to the process of absorbing again.
One useful trick is to think of resorption as reabsorption without the “a" and “b”—it’s lost these letters. Therefore, resorption is the word that describes loss.
