What is the meaning of the term viscid?

The term "viscid" specifically refers to a substance that has a sticky or adhesive quality. It is often used in a medical or scientific context to describe liquids, such as mucus, that have a thick, glutinous consistency. Viscid substances tend to cling to surfaces and resist flow, which can be important in various biological processes or when describing certain medications or bodily secretions.

Other terms provided do not accurately capture the meaning of "viscid." For example, the term describing a liquid consistency relates more to the overall state of a liquid rather than its adhesive properties. Similarly, "sour in taste" pertains to flavor, and "transparent in nature" refers to clarity or light transmission properties, which are distinct from the characteristics implied by the word "viscid." Thus, the choice that aligns with the definition of "viscid" is the one denoting a sticky or adhesive quality.
