I am searching for a word, an adjectival form of the word "argument" in its sense as: "a statement or series of statements for or against something." The word "argumentative" does not work. I am looking for an adjective that can replace "opinion" in the following sentence: "It demonstrates most of the features of opinion writing and ... " I am not at liberty to rephrase the sentence, but a different adjective -- if there is one more precise than "opinion" -- could be used. Would anyone recommend using the word "argument" as an adjective?
Although the term argumentative can be used here, the more common term for this type of work is discursive writing. Here's a definition the adjective discursive from Merriam Webster:
1 a : moving from topic to topic without order : rambling
1 b : proceeding coherently from topic to topic
2 : marked by analytical reasoning
Note that this usage derives from the last two definitions, not the first!!!
Here's an example taken from the Cambridge University website for IELTS teaching:
- The texts may be written in different styles, for example, narrative, descriptive or discursive/argumentative.
It is correct to use argumentative writing in your example. Here argumentative means using reasoning.
