I am facing a problem and I would be grateful if you can help me

I have a list of words like

And I have a datafile like


I want to find Patterns of “x.*x” where x are the words mentioned, meaning that each line with start with X and followed/finished by X, such as


But I need each of them to be saved in a different file so one file for “the.*the” and so on.
I would previously create a acceptfile of the words, such as


and read a normal pattern from an acceptfile using

Code:

Grep -F  -f acceptfile.txt mainfile.txt > outputfile.txt

But the problem here is that I look for a substring and not a single word and GREP acceptfile is not reading my “x.*x” if i type that in my acceptfile
On the other hand, I used to use grep for substring patterns matching

Code:

grep 'The.* of' main.txt > output.txt

but now that I have about 10 words and I want all of them to be compared to each other, I would have around 100 patterns of “x.*x” and I don't want to manually sit and put them in
I am new to unix but I am sure there should be way to do this but not yet sure how.

Note: I don't necessary need to use GREP but this is just what I am familiar with now but happy to learn new things

I would be amazing if you can help me

Thank you in advance

or it may be simpler to say i have a array or file called X

and another one called Y

the command looks like this

Code:

grep 'The.* of' A1-5word.txt| sed -n -e "s/.*\(The[^)]*of\).*/\1/p" > the-of-lines.txt

i guess i would need a loop to go through each one of the Xs and each one of the Ys and put them either in separate column or file like

I am really trying my best but dont know what to do
