The main textual features in argumentative texts are given by textual and lexical items, that is, textual devices which are words used to enhance the effectiveness of the argument (i.e. declarative verbs, adversative, summative, concluding connectors, syntactic structures).
The following five features make up the structure of an argumentative essay:
•Introduction and thesis.
•Opposing and qualifying ideas.
•Strong evidence in support of claim.
•Style and tone of language.
