Is contentual a proper word? I saw in Wiktionary that it is considered to be a proper word:
contentual
adjective
Relating to content (as apposed to context)
However, I have not seen it cited in any major dictionaries (Websters, Oxford, Collins etc.).
If the reason it is not in these dictionaries is because the word "contentual" is not considered to be a proper word, why is this so?
