    I must be thankful to my friend Cheran, who shapes my thoughts by getting it to the root and evolve from there. Our meetings are very constructive and thought provoking. It is good to be mentored by genius like him.

    An attempt to understand :- Syntax, Sematics and Pragmatics.

    C.W. Morris in his Foundations of the Theory of Signs (1938) organizes semiotics, the study of signs, into three areas:
    >> syntax (the study of the interrelation of the signs);
    >> semantics (the study of the relation between the signs and the objects to which they apply); and
    >> pragmatics (the relationship between the sign system and the user)

    Syntax:
    From WordNet
    01. The grammatical arrangement of words in sentences
    02. a systematic orderly arrangement
    03. studies of the ruels for forming admissible sentences

    From Free On-line Dictonary of Computing (FODC)

    The Structure of strings in some language.

    -> abstract syntax
    -> concrete syntax
    -> transfer syntax

    Semantics
    From WordNet
    01. the study of language meaning

    From FODC
    The meaning of the string in some language as opposed to {syntax} which describes how symbols may be combined independent of their meaning.
    PDCA - Plan Do Check Act

    Come on I have problem at stage 2 (Do) itself. How do I get out of this problem? Hmmmm do I have to learn some new problem solving techniques. Eh? DO DO DO DO DO DO DO DO DO, DO What you have planned.

    I started this blog to learn blogging, improve communication skill and of course slowly but steadly move toward the mainstream blogger. I hope my blourney (blog+journey) will be smother and keep up the pace.
