What does "unquenchable" mean?

The term "unquenchable" refers to something that cannot be satisfied, subdued, or extinguished. It is often used to describe desires, passions, or thirsts that are so intense that they cannot be wholly satisfied. For example, someone may have an unquenchable thirst for knowledge, indicating that their desire to learn is boundless and cannot be met fully.

The alternative choices do not align with this definition. For instance, stating something is possible to extinguish directly contradicts the meaning of "unquenchable," as it implies that something can be extinguished or satisfied. Similarly, being capable of being satisfied suggests that the entity can be quelled or fulfilled, which goes against the idea of being unquenchable. Finally, describing something as temporarily extinguished indicates that it can be subdued, at least for a time, which is not consistent with the idea of something being unquenchable. Thus, "impossible to quench" accurately captures the essence of the word.
