okay, I've 3 sections to some site

/section-1/
/section-2/
/section-3/

I'm not going the youngster pages to possess a mention of the them within their permalinks

/section-1/apple/
/section-1/orange/
/section-1/blueberry/

The 2nd level pages in every section won't ever have a similar slug or title. I would like the 2nd level pages to appear such as this within their url:

/apple/
/orange/
/blueberry/

How do you do that? Pleased to operate in .htaccess

In your admin dashboard, under Configurations -> Permalinks, you are able to select a custom structure for permalinks, In my opinion this is exactly what you are searching for.
