Abdominal pain can be caused by many conditions. However, the main causes are infection, abnormal growths, inflammation, obstruction (blockage), and intestinal disorders. Infections in the throat, intestines, and blood can cause bacteria to enter your digestive tract, resulting in abdominal pain.
Most obviously, a hyphen is used to indicate that a long word has been broken off at the end of a line: You should avoid such word splitting whenever possible. If it is unavoidable, try to split the word into two roughly equal parts, and make sure you split it at an obvious boundary. Do not write things like.
The hyphens are unnecessary in sentence 1 because the phrase five years of age is not being used as a single adjective. In sentence 2, however, the phrase five-year-old is being used as a single descriptor for the noun boy.Not one of the words in that phrase would work alone; that is, he is not a five boy, a year boy, or an old boy. We have to pull all those words together to form a single adjective.The hyphen in sentence 3 is correct because we always use a hyphen in compound numbers between twenty-one and ninety-nine.he descriptions too-tall-to-tango and bramble-covered are also correctly hyphenated in sentence 6 because they precede the nouns they modify. Notice that we did not include the word tough in the hyphenated phrase too-tall-to-tango because it is a separate adjective.
