drive someone up a wall/the wall

[dean1]

Hi. I'd like to know if the article 'a' is also acceptable. I google it on the internet and have found both entries. Do both mean the same thing?

Both work. I'm not 100% sure of the difference in meaning though, but it probably has to do with specifics:

[1] 'the wall', the extreme position or situation is known.
[2] 'a wall', the extreme position or situation is left undefined.

Many thanks.

You're welcome.
