Example Input: In math, we use the term series a lot, and there are many types of series. How should I craft my sentence when I have three different ones in mind to talk about? Should I settle down for a less mortal alternative of 'list of series' or something like that? The existing question on The possessive and plural forms of 'series' suggests the usage of series'. But is that all? If that's the only solution, then could you please explain the usage of apostrophe symbol at the end? Is that a plural marker or a possessive marker, or both?.
Example Output: Series (like deer, salmon, and sheep) is pronounced and spelled the same in the plural as in the singular. If either the singular or the plural is used as a possessive, an apostrophe is added to show that in print, though there is no pronunciation difference in speech. Thus, The series doesn't converge. (singular) The series don't converge. (plural) This series' limit is unknown. (singular possessive) These series' limits are unknown. (plural possessive) More examples can be seen here.

Example Input: Sometimes I go through articles and find the expression utilize, I've always been wondering if there are special cases in which it should be used instead of used. Also because google ngram clearly shows that used is used (sorry for that ;D) much more. Thanks for your help and happy new year!.
Example Output: Some dictionaries gloss utilize as using something for a purpose that it is not normally employed for. But prescriptive grammarians are pretty clear on such use. Fowler in Modern English Usage (p670) says: If differentiation were possible between utilize and use it would be that utilize has the special meaning of make good use of, especially of something that was not intended for the purpose but will serve. But this distinction has disappeared beyond recall; utilize is now ordinarily treated as a LONG VARIANT of use. A form is enclosed herewith for favour of your utilization is an example of the pretentious diction that prefers the long word. Partidge in Usage and Abusage (p343) is typically blunt: utilize is, 99 times out of 100, much inferior to use; the other one time it is merely inferior. And here is the more contemporary Grammar Girl's similar take on the issue: [link] Nevertheless, this Usage Note from TheFreeDictionary indicates when utilize might indeed be the better choice: A number of critics have remarked that utilize is an unnecessary substitute for use. It is true that many occurrences of utilize could be replaced by use with no loss to anything but pretentiousness, for example, in sentences such as They utilized questionable methods in their analysis or We hope that many commuters will continue to utilize mass transit after the bridge has reopened. But utilize can mean 'to find a profitable or practical use for.' Thus the sentence The teachers were unable to use the new computers might mean only that the teachers were unable to operate the computers, whereas The teachers were unable to utilize the new computers suggests that the teachers could not find ways to employ the computers in instruction.

Example Input: it refers to a discrete life form that has properties of mind (i.e. experience and character, cf. sentience).
Example Output:
cf., an abbreviation for the Latin word confer (the imperative singular form of 'conferre'), literally meaning 'bring together', is used to refer to other material or ideas which may provide similar or different information or arguments. It is mainly used in scholarly contexts, such as in academic (mainly humanities, physics and biology) or legal texts. It is translated, and can be read aloud, as 'compare'. -wikipedia
