From the Latin unus, a single and fero, to carry, to produce: to produce only once (a year). It is customary to say of some plants to distinguish them from the biferous ones, that they fruit twice, as, for example, fig trees. Some only produce figs in September. Although in my land they also give brevas in June-July unless the environmental conditions are very negative. From this fact comes the saying from figs to figs, comparable to that of Easter to bouquets, because from one event to the other it takes more or less a year.
* Only one "like" per meaning and day, the more "likes" the meaning will appear higher in the list
