1) Thanks for your explanations
2) "wereduck" like in "werewolf" ... hoho <img src="images/graemlins/smile.gif" alt="" /> .... I get it, now ...... Thanks again.
3) as Max said, no need to apologyze ; I like to learn something new, every day I visit this forum.
4) BTW, about apologies, I have to offer mine's to all the ETS forumits (or forumnists ??) , for the way I smash up english grammar. Sometimes, re-reading a post, I try to edit it, to correct a misspelled word or a wrongly conjugated verb .... but I guess I leave many uncorrected ones ! <img src="images/graemlins/confused.gif" alt="" />
