You can try using sed option...inside for loop

Code:
sed 's/accelerate/acceler/g' inputfile

Thanks

The example you're giving for this question is so absurd I have to ask: is this homework?

So you need to check the current state and act differently depending on the current state
Code:
if accelerate=$(grep accelerate inputfile); then 
   sed 's/accelerate/acceler/g' inputfile
else
   sed 's/acceler/accelerate/g' inputfile
fi
