Grep get everything except matching

Lets say I have a text file that says:

Hello my name is agz. I am asking a question that is important. 

If i type: grep -v "is" /path/to/file, I should get no output because both lines have "is".

If i type: grep -o "is" /path/to/file, i should get:

is is 

However I want to get:

Hello my name agz. I am asking a question that important. 

(just missing the is) Is there a way to achieve this using grep and minimal regex?

grep isn't the right tool for this job. sed is.

$ sed 's|is||g' test.txt Hello my name agz. I am asking a question that important. $ sed 's|is ||g' test.txt Hello my name agz. I am asking a question that important.
