Current Grammar

free* appears 147 times in the PEG grammar

indicator <- (UI-clause / CAI-clause) NAI-clause? / DAhO-clause / FUhO-clause

Proposed Grammar

Eliminate free* from every current rule and add it to:

indicator <- (UI-clause / CAI-clause) NAI-clause? / DAhO-clause / FUhO-clause / free

Rationale

Since the PEG grammar allows infinite lookahead, there is no point in having to learn the 147 places where free is currently allowed (or the fifty something places where it is not allowed, depending on how you count). It is easier to learn that it is allowed everywhere, like indicators.

Notes

The exceptions to where indicator/free would be allowed are:

  • After a right grabbing magic word (ZO, ZOI, LOhU, ZEI)
  • (number / lerfu-string) MAI-clause can't come after a number or lerfu-string that is not part of it, because it would absorb it.
  • vocative can't come after a COI-clause that is not part of it, because it would absorb it.
