Etymology: Old English "scyldan" meant "to owe" or "to be obliged to," and it was the verb behind the familiar "shall" and "should." Its story begins with a simple idea of debt: someone who owed a sum was bound to pay it, and "scyldan" expressed that obligation. It belonged to the same Germanic family as "guilt" and "shield," a link that hints at the older sense of being answerable for a wrong. Over time the verb shed its meaning of owing and took on a grammatical role. Because "scyldan" was used to express obligation, it gradually became a helper verb for expressing duty and necessity. In Middle English the forms "shall" and "should" were established, with "should" retaining the sense of obligation most clearly, as in "you should go."
