Although many people in my district don't discriminate between venom and poison,I think they have a very important difference.the difference is in the meanings. for more clarity I should say venom is applicable to cases that you are passive and poison is applicable to those you are active.For example a frog is venomous but a snake is poisonous.
All I said till here was just prelude to my main words.
I start with a question, what are "words " type? Are they poisonous or venomous? I think.
they are not either venomous or poisonous! but they produce them for others!
