| 3 Kinds of Conjunctions | Coordinating, Subordinating, Correlative |
| Coordinating (FANBOYS) | For, And, Nor, But, Or, Yet, So — connects grammatically equal words/phrases/independent clauses |
| Subordinating | because, if, although, since, until, while — introduces a dependent clause |
| Correlative | Tag-team pairs: not only-but also, either-or, neither-nor, both-and, not-but, whether-or |
| Although/Though | Pairs only with "Yet," never with "but" (double-conjunction error) |
| Because/Since/As | Never paired with So/Therefore/Thus (same double-conjunction trap) |
| Lest | Always followed by "should," never "not" (negative already built-in) |
| Supposing / If | Same meaning — cannot be used together in one clause |
| Wonder/Not sure/Not know | + if/whether (not "that") |
| "or not" in clause | Forces "whether" — never "if" or "that" |
| Doubt/Doubtful — Affirmative | + if/whether |
| Doubt/Doubtful — Interrogative/Negative | + that |
| Correlative position rule | The correlative word must sit immediately before the exact part being compared, on both sides of the pair |
| Not either | … nor (never "or") |
| Seldom or never / Seldom if ever | Fixed emphasis phrases — do not substitute "ever" for "never" in the first, or "never" for "ever" in the second |
| Since — Conjunction (Time) | जब से — connects two clauses about a starting point in time |
| Since — Conjunction (Reason) | क्योंकि — connects two clauses giving a reason |
| Since — Preposition | उस समय से — followed directly by a noun |
| Since — Adverb | के बाद से — used alone, nothing follows |
| Unless | = except if; denotes CONDITION |
| Until | = up to the point in time; denotes TIME |
| Unless and Until | Valid emphasis structure when used together (not an error) |
| Unless + double negative | Never use "not" after unless (unless already means "if not") |
