These days, virtually every public talk speaker thinks it's interesting and intellectual to include a dictionary definition of some word. Often the word is in common use and needs no explanation, such as 'exercise', or 'knowledge', or whatever.
Now contrast that to all of the words that the WT has it's own meaning for, and referencing a dictionary for the common understanding of it would be viewed unfavourably.
Words like 'generation' or 'men' (as in Jesus is mediator between God and 'men' - 1Tim 2:5-6).
What words have the WT redefined that you know about? - I'd like to compile a list if possible.
