The word impermeable (ɪmˈpɜːmɪəbəl) is spelled using the prefix "im-" which means not or without, and the root word "permeable" which means allowing liquids or gases to pass through. The spelling may be a bit challenging as it has several silent letters such as the "e" at the end, and the second "e" after the letter "r". Nonetheless, mastering the spelling of this word is crucial in scientific studies where impermeable materials are utilized in constructing waterproof structures.
The term "impermeable" is an adjective that describes a substance or material that does not allow any liquid or gas to pass through it. It refers to the inherent quality of an object to resist the flow, seepage, or penetration of any fluid or gas.
When applied to a physical object, such as a fabric, membrane, or barrier, impermeable indicates that the substance is completely resistant to absorption. Thus, it forms an impenetrable barrier that prevents the passage of liquids or gases. This characteristic can be observed in raincoats, rubber gloves, or waterproof membranes, as they effectively repel water, preventing it from permeating through their surface.
Additionally, the term can be used figuratively in a broader context to describe objects, substances, or conditions that are unable to be influenced or affected by something external. For instance, someone might describe a leader as having an impermeable personality, meaning that this person is not easily swayed by external factors or opinions.
In summary, "impermeable" is an adjective used to describe substances, materials, or conditions that resist the flow or penetration of liquids, gases, or external influences. This term is often employed in both a literal and metaphorical sense to convey the concept of non-penetration or non-affectedness.

The word "impermeable" originated from the combination of two Latin roots: "im-" meaning "not", and "permeabilis" meaning "passable" or "penetrable". The Latin root "permeabilis" is derived from the verb "permeare", meaning "to pass through" or "to penetrate". Thus, the word "impermeable" retains the same meaning, describing something that cannot be penetrated or passed through.
