How to replace a string contains in another string using regular expression

what about this pattern?

w+\w+‍

Thanks Martin,

The pattern works perfectly for replacing but how can I tell to replace before and after words if they're matched?

here is the example if signer = nassafari => Replace nassafari with "Replaced".

if signer = aamhatala => Replace  aamhatala with "Replaced".

Thanks

I'm not sure I understand what you mean.

the pattern I suggested replaces any two consecutive words split by single backslash. do you mean to replace only exact string pattern? so eg if there appear nassafari in the text then replace it, but if there appears eg. anssafari then do not replace it?

if so, then your pattern simply should look like

na\ssafari‍

I figured that out,

na\ssafari will replace nassafari in a string.

great!

if you've got a solution please mark question answered.
