No, as I said, the largest single addressable unit that fits into a GPR.

> Word Boundary = Address divisible by number of bytes that represents a single addressable unit.

With the above addition, correct.

> Example Single Word length = 16 bits then a word boundary is any address divisible by 16.

I think this is a typo, but just to make sure: No, divisible by two
I agree to the modification of the definition of 'Single Word'.

Please provide me arguments as to why you say 'No, divisible by two' with regards to ‘word boundary'. Is it that word boundary depends upon the type of data we are referring to i.e. depends upon the sizeof of the data type. Hence for a four-byte-sized integer the word boundary will be of multiples of 4 and for two-byte-sized integer the word boundary will be multiples of 2 respectively.

Thanks in advance.
 
PPI::Token::Word(3)					User Contributed Perl Documentation				       PPI::Token::Word(3)

NAME
PPI::Token::Word - The generic "word" Token INHERITANCE
PPI::Token::Word isa PPI::Token isa PPI::Element DESCRIPTION
A "PPI::Token::Word" object is a PPI-specific representation of several different types of word-like things, and is one of the most common Token classes found in typical documents. Specifically, it includes not only barewords, but also any other valid Perl identifier including non-operator keywords and core functions, and any include "::" separators inside it, as long as it fits the format of a class, function, etc. METHODS
There are no methods available for "PPI::Token::Word" beyond those provided by its PPI::Token and PPI::Element parent classes. We expect to add additional methods to help further resolve a Word as a function, method, etc over time. If you need such a thing right now, look at Perl::Critic::Utils. literal Returns the value of the Word as a string. This assumes (often incorrectly) that the Word is a bareword and not a function, method, keyword, etc. This differs from "content" because "Foo'Bar" expands to "Foo::Bar". method_call Answers whether this is the name of a method in a method call. Returns true if yes, false if no, and nothing if unknown. TO DO
- Add "function", "method" etc detector methods SUPPORT
