Thank you so much all for your direction. I am still over the edge for removing these words out of the story, and I do think I don't have any other 'complex' words in it. So I would like to try it in the whole story setting and really see if it makes it any worse. Of course , first , I do have to get the story right

Vijaya, Keila, Deenalapomy01, that was surprising piece of information for me. Thank you for sharing. I thought just reverse , as PBs would be read by much younger range and so simpler words only. The blog was good piece, it set my mind at ease for PBs.
Can I cheat and just say my book is only PB and not EZ Readers'?

Jeanne, Laurel, thanks for explaining the ease of these words. I think I would be leaving these words in for now.
Hi Debbie and Verla (it just amazes me how many places your eyes are and responding at the lightening speed everywhere

! Thanks!)
The story is narrated by author, so it's not in first person POV , nor by a child or so. And as I type, I am also revising the manuscript once more (that's how I am spending my holiday today,

yes). I would be very grateful for the SCBWI critique post responses. I will be posting it shortly. Thanks for giving the example of rendezvous and raucous ruckus

I am going to apply the advise while revising, are my words easily explained. Also , maybe the word 'dithered' is used twice I'll limit it once only. This was also suggested in a critique comment.
Guess what! While doing this research, I ended up somehow searching the word CANTAKEROUS, and it does exist in a PB , actually right in a title. I was so happy. But yes , I remember, PBs different than EZ readers. I will post the whole story shortly. Meanwhile , just sharing:
