Reborrowing

The word flan itself is a relatively recent addition to English, adopted on our behalf from French by the chef Alexis Soyer (a Frenchman working in England), but in that form it is in fact simply a reborrowing of a word which originally crossed the Channel in the 13th century as flawn, denoting some sort of custard tart or cheesecake.

The borrower will usually argue that the accordion should be considered as a reborrowing of debt already repaid, and therefore should be a redraw of tranche A first.
