Is there an alternative adjective to 'written' with an -al suffix?

I'm ideally looking for a single word adjective with an -al suffix. i.e. similar to 'verbal', and 'visual' but that relates to written communications rather than spoken or illustrative communications. Does such a word exist?

I'm trying to create a bit of wordplay about different communication methods.

Thank you!


Solution 1:

One normally uses textual to indicate that something is written, for text is normally written.

Solution 2:

You could try 'scribal' - of or relating to a scribe... 'Scriptal' does not, unfortunately, seem to exist!
