Having the option of not using a word in a combinatory attack

[JuanPelota]

Hello

I am trying for sveral wks to crack an old ethereum wallet (#sigh)

I have a blurred idea of what the password could be. To ease combinatory attacks and workload on my old CPU, I'd like to know if there is trick to avoir using a word from a list in a combinatory attack. 
Example

My password might be 

Alphabeta99gamma or Alphabetagamma or Alphabeta9gamma

I'd like to makee combination from two lists
Let's say on the left part I have

Alfa
Alpha
Alfabeta
Alphabeta
Alfabéta
Alphabéta

On the right I would have


"blank"
9
99

and then a third part I could add lately


So that in the end  I could have a (big) list of variation of the first part of my passsword without the second part thanks to the "blank" 

I guess  I could just pass a list  of the left part of the password but actually it's a very simple example here and my password might be 50+ characters thanks to a passphrase with different characters between words, you get the idea ? 

Thanks

use:
combinator left.txt right.txt > combi.txt

resulting in combi.txt
Alfa
Alfa9
Alfa99
Alpha
Alpha9
Alpha99
Alfabeta
Alfabeta9
Alfabeta99
Alphabeta
Alphabeta9
Alphabeta99
Alfabéta

Alfabéta99
Alphabéta
Alphabéta9
Alphabéta99

thank you for your reply, I have not expressed myself well.

The trick is that my password might be a combination of 11 or 12 words, so it makes a lots of combinatory and I get lost in combining all of this, especially when I add typos and slight variations in words. I will aslo dig the prince attack stuff

[Snoopy]

that would quite huge regarding the combinations, so yeah, give princeprocessor for that a try, there are options to tell prince to use min/max words from a list

how to use princeprocessor

[Snoopy]

well prince processor help is quite straight forward, in your case the needed options would be

--elem-cnt-min=NUM Minimum number of elements per chain
--elem-cnt-max=NUM Maximum number of elements per chain

so min would be 11 max 12

feed output from pp to hashcat through pipe like

pp64 --elem-cnt-min=11 --elem-cnt-max=12 yourlist.txt | hashcat with appropiate options (mode etc.)

but be aware 11 or 12 combinations from a quite huge list will result in na even more gigantic list
