Returning from time to time; as recurrent pains of a disease.

In crystallography, a recurrent crystal is one whose faces, being counted in annular ranges from one extremity to the other, furnish two different numbers which succeed each other times, as 4, 8, 4, 8, 4.

In anatomy, the recurrent nerve is a branch of the par vagum, given off in the upper part of the thorax, which is reflected and runs up along the trachea to the larynx.
