You could search for this:

(?<!\btexts?\b.+)texts?

Then replace with this:

paragraph

Basically a negative lookbehind so you only find the first "text" or "texts" and then "text" or "texts".  Replace is simple as you are finding the first occurrence so you just replace it with whatever text you like.

Thanks Paul, works perfectly.

You could also simply look for the first occurrence, such as with

^(.*?)(\btexts?\b)

and replace with

$1paragraph

Tested and this formula captures more than it should.

Mea culpa, it should have been

^(.*?)(\btexts?\b)(.*)$

$1paragraph$3

This one matches the whole segment.

I believe it's supposed to.  The use of the backreferences in the replace will put things back as intended.

Yes, tested and verified.
