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.
Possible Duplicate: When is it necessary to use a hyphen in writing a compound word? Some English texts, use the prefix sub put before a given proper word with - between them, for example sub-zero, while in the Mathematical contexts there is no such that -, for example subgroup or subfield.s a general rule, the hyphen is more likely to be used in situations where you're expected to read sub- as a separate unit, and it gets lost when the entire compound word gets common enough to be perceived as an entity in and of itself. As such, there can be migration from one to the other over time.
