Seems to me there should be a word "Soo" like we have "Too"

Sometimes when I am writing stuff I just think there are obvious words missing from the English language that really should exist. One of these is 'soo'.

So, we have 'so' with just one letter "o". And it does fine in those places where you just need to use a regular 'so'. In cases like: We were going to the lake, so Julie wanted to come as well. Or maybe: The recipe called for an egg, so I added an egg.

But sometimes you just feel the need for a bigger harder so—a so with two "O"s just like we have a to with two "O"s.

Like, if I replace the 'too' with 'so' in the following it just seems to lack some intensity.

"This piece of wood was too hard to chop" becomes "This piece of wood was so hard to chop". It feels to me like I am replacing a hard too with a kind of soft-ish so.

Surely it would be better as: This piece of wood was soo hard to chop.

Or "It is soo hard writing this post and making the point I am trying to make" seem to have more impact than "It is so hard writing this post and making the point I am trying to make".

Just a passing thought . . .
