does the reader consider “person” or any applicable noun referencing the reader’s being to be recursively defined, ie. (excuse the bad EBNF)

<person> ::= <person> | <person> <person>

or does the collective / system require a specifically defined plural form?

<people> ::= <person> | <person> <person>

to clarify: this is more aimed at preference / ideals, not necessarily just what is acceptable, but any interpretation is fine
