आकाङ्क्षार्थस्य संयोगाद्रसभेदार्थिनामिव ।
In plain words
A sense that is still reaching for something gets joined to what it reaches for — as happens with people who want a variety of flavours.
Close to the Sanskrit
Because of the conjunction of a meaning that has expectancy — as in the case of those who desire a variety of flavours.
