The document outlines 17 rules for using conjunctions correctly in English sentences. Some key points covered are:
- Correlative conjunctions like both...and and not...but should be used together to include or exclude structures.
- Question words like what, when, and how can introduce indirect questions but should not be followed by auxiliary verbs.
- Comparisons use conjunctions like "as...as" while "so...as" is used in negative comparisons.
- Time conjunctions like until and unless differ in meaning and cannot take negations before the clause.
- Doubting conjunctions like if/whether and that are used depending on sentence type.
- Pairs like not only...but also must be used
