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.
Compound terms, those having more than one word, are hyphenated here in order to indicate their integrity as a single concept and to avoid confusion in cross-referencing them in the definitions of other terms. They are not normally hyphenated in normal usage.
