If we have: 1234 value x synonym y x Is this valid Forth? 9876 to y Relevant bits of the Forth 2012 standard are: 6.2.2295 TO "An ambiguous condition exists if name was not defined by a word with “TO name run-time” semantics." As y is defined by SYNONYM presumably the above is an ambiguous condition. This seems wrong to me, after all one of the uses of SYNONYM is to redefine a word with the same name in a different wordlist and that, apparently cannot be done with VALUEs Incidentally Gforth gives 1234 value x ok synonym y x ok 9876 to y :3: error: Invalid name argument 9876 to >>>y<<< Having written the above, I just realised that exactly the same question applies to a SYNONYM of a deferred word and using IS on the synonym. defer p synonym q p ' some-def is q Again Gforth rejects this, but does accept ' some-def ' q defer! which works correctly. If these uses of SYNONYM are ambiguous conditions then it makes SYNONYM less useful than it could be. -- Gerry
