Comma= The comma has several uses in English grammar, all related to marking-off separate elements within a sentence:
1. Introductory words and phrases: Once upon a time, I didn't know how to use commas.[5]
2. Parenthetical phrases: The parenthetical phrase has an important, often misunderstood, use. It is often used for thought interruptions. Information that is unnecessary to the meaning of the sentence is commonly set off and enclosed by commas. If the information is necessary, no commas should be used.
* Restrictive and non-restrictive use: The sentences I cut down all the trees, which were over six feet tall and I cut down all the trees that were over six feet tall look similar but in fact have very different meanings. In the first sentence all the trees were cut down, and a detail (their height) is added. In the second case only some trees were cut down, those over six feet tall. There may have been shorter trees too, but none of them were felled. In the first case, which were over six feet tall is set off by a comma because it is a non-restrictive clause (i.e., its removal does not alter the meaning of the sentence). In the second, that were over six feet tall is a restrictive clause and takes no comma (because if you left it out, the sentence would then say that all the trees were cut down, not just the ones over six feet). Note that in British English, the restrictive clause example can be written as I cut down all the trees which were over six feet tall as the relative pronouns which, who, and whom are interchangeable with that.
Coma= In medicine, a coma (from the Greek κῶμα koma, meaning deep sleep) is a profound state of unconsciousness. A comatose patient cannot be awakened, fails to respond normally to pain or light, does not have sleep-wake cycles, and does not take voluntary actions. Coma may result from a variety of conditions, including intoxication, metabolic abnormalities, central nervous system diseases, acute neurologic injuries such as stroke, and hypoxia. It may also be deliberately induced by pharmaceutical agents in order to preserve higher brain function following another form of brain trauma.
That might clear some things up.
