Surrenders or gives up, often under pressure; the third-person singular present form of capitulate.
From Latin 'capitulare' (to divide into chapters or to surrender). The modern meaning emphasizes surrender, though the original sense of organizing by chapters still appears in formal contexts.
Interestingly, whether you're organizing a book or surrendering in battle, you're using 'capitulate'—in one case you're reducing ideas to chapters, in the other you're reducing your demands to surrender terms!
