fall ill

The phrase "fall ill" has its roots in Old English and is a combination of two distinct words: "fall" and "ill." "Fall" comes from the Old English word "feallan," which meant "to drop, sink, die, decay." This in turn is derived from Proto-Germanic *fallaną and Proto-Indo-European *phol- meaning "to fall." Over time, the meaning of "fall" expanded to include a change of state, not just a physical descent. For example, one could "fall asleep" or "fall in love." "Ill" comes from the Old Norse word "illr," meaning "evil, bad, wicked, difficult." It entered the English language around the 12th century, largely replacing the Old English word "yfel" (evil). Initially, "ill" carried a strong moral connotation, referring to something morally bad or wicked. However, by the 13th century, it began to be used to describe physical ailment or discomfort. The transition from moral badness to physical sickness is a common linguistic phenomenon, as suffering and misfortune were often associated with moral failing in earlier times. The combination of "fall" and "ill" to mean "become sick" likely emerged in the late Middle English period. The use of "fall" to denote a transition into a particular state, combined with "ill" indicating a state of sickness, naturally formed the phrase. It emphasizes the suddenness or the onset of the sickness, as if one 'falls into' the state of being unwell. Examples of its usage can be found in literature dating back several centuries. For instance, in Shakespeare's plays, variations of the phrase appear, reflecting its established use in the language. The phrase has remained remarkably consistent in its meaning and usage through the centuries, standing as a clear and concise way to describe the onset of sickness. In modern English, "fall ill" is still commonly used, often in more formal contexts or when describing a sudden or unexpected illness. It carries a slightly more dramatic or serious tone than simply saying "get sick" or "become sick." Its enduring presence in the lexicon highlights the power of combining simple, ancient words to create a vivid and understandable expression.
