fortification

Kenett states that the military works still known by the name of Tadmarten Camp and Hook-Norton Barrow were cast up at this time ; the former, large and round, is judged to be a fortification of the Danes, and the latter, being smaller and rather a quinquangle than a square, of the Saxons.

Compare the nutrition information label of a regular ready-to-eat fortified cereal with that of a presweetened brand and you'll note that, although the sweetened one's sugar content is higher, the fortification is virtually identical.
