What does the verb "adapt" primarily mean?

The verb "adapt" primarily means to make suitable for a new purpose. This concept involves altering or modifying something so that it can function effectively in a different context or meet new conditions. For instance, when a person adapts to a new environment, they adjust their behavior and practices to align with the norms and requirements of that setting.

This application of "adapt" emphasizes flexibility and the ability to adjust to varying circumstances, which is key to how it is used in various contexts. In contrast, the other choices reflect different meanings that do not encompass the full scope of what "adapt" signifies. The second choice speaks to repair rather than adjustment for suitability, the third option suggests an increase in size rather than modification for purpose, and the last option relates to marketing rather than making something suitable for a new function.
