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?
