Argument: an attempt to persuade a
reader (or listener) to accept
something. An argument must have a
conclusion and at least one reason.
Conclusion: the conclusion of an argument
is a statement of something that the writer
(or speaker) wants the reader (or listener)
to accept based on the reasons given.
Reason: a statement that aims to persuade
the reader to accept a conclusion.
Claim: a statement
or judgement that
can be challenged
(not supported by
reasoning)

Counter-assertions,
counter-arguments, hypothetical
reasoning and assumptions
Counter-argument: an
additional argument that
is against what the
conclusion seeks to
establish. The writer
normally presents the
counter-argument in
order to dismiss it.
Counter-assertion: a reason that would
support an opponent's argument
indicator words:
although, despite this,
however, it has been
said, contrary to this,
on the other hand,
some may argue
Hypothetical reasoning: looks at the consequences that
might occur if something were the case. Usually using
form 'if this... then that...'. Indicator phrases include: if,
provided that, on condition that, given that...then...'
assumption: a missing reason in the argument. The writer
accepts the assumption, but has not stated it. The
assumption is essential for the conclusion to be drawn
Identifying evidence
and examples
Fact: information that can be verified and that is held to be true
Factual claim: a statement or judgement based on
information that can be verified and that is held to be true
Evidence: something that is used to develop or
support a reason. Evidence is often in the form of
numerical data, an estimate, or a factual claim
Example: something which is used as evidence
because it is characteristic of the same kind of things
or because it can serve to illustrate a principle
