This question already has an answer here:

The word series seems to generally refer to a group which I would think makes it a singular reference, however the ies ending is also a common way to modify a singular noun into a plural noun (eg., puppies, fancies, harpies).

So is series plural or singular, and if plural, what is the singular version?

Series is singular and doesn’t change in the plural. Its spelling originates from Latin:

1610s, "a number or set of things of one kind arranged in a line," from Latin series "row, chain, series, sequence, succession".
