@Dan-Engel, happy to help!

In addition to the list I will provide below, I would recommend creating your own extensive list of keyword indicators that you come across in the lessons and questions.

Words that Introduce Sufficient:
- if
- when/whenever
- where/wherever
- the only
- people who
- always
- never
- all
- every
- each

Words that Introduce Necessary:
- only if
- only when
- only where
- only
- must
- necessary
- requires

Does this make sense? Please let us know if you have any additional questions and best of luck with your studies!

Thank you. What about indicators for Premises (since...)and Conclusions (thus...)

would Sufficient / Necessary indicators fall under the step of determining whether the argument is valid?

Words that indicate a Premise:
- since
- because
- given that
- for
- for the reason that
- in that
- as indicated by
- may be inferred from
- as

Words that indicate a Conclusion:
- therefore
- hence
- thus
- consequently
- it follows that
- so
- accordingly
- it can be concluded that
- we may infer
- for this reason
- as a result

Sufficient and Necessary indicators and their diagrams can be used to determine whether an argument is flawed or valid. This process is explained in great detail in the Sufficient & Necessary lesson.

Again, I would recommend adding to this list as you study. Hope this helps!
