Clause Types — Map

Here's the thing. You've got a sentence in front of you — a school essay, a work email, a text you're overthinking at 11pm — and you know something about clauses is getting in the way. The trouble is, "clause types" isn't one topic. It's a whole family of them, and you don't need to learn every branch today.

So this page is only a map. No definitions, no drills, no worked examples — that's what the linked articles are for. Here, I just point you to the right door.

Already need the basics behind you? → Pillar 1 · What Is a Clause? — start here if you're not yet sure what a clause even is. → Pillar 2 · Relative pronouns and Subordinating conjunctions — the toolkit these clause types use. → 2.1 · Sentence Types — how clauses combine into simple, compound, and complex sentences. → Pillar Hub — the full map, if you've lost your bearings entirely.

Where to go next (Pillar 3 · Clause Types)

3.1 — Main (Independent) Clauses. The clause that can stand alone as a complete sentence — the backbone everything else attaches to. → Go to 3.1 Main Clauses: The Backbone of Sentences

3.2 — Subordinate (Dependent) Clauses. The clause that can't survive on its own, and how to spot the fragment when it tries to. → Go to 3.2 Subordinate Clauses: How They Hang On

3.3 — Adverbial Clauses. Clauses that act like adverbs, telling you when, why, how, or under what condition something happens. → Go to 3.3 Adverbial Clauses: When, Why, How, and What If

3.4 — Noun Clauses. Clauses that act like nouns, filling the subject or object slot ("what she said", "that he left early"). → Go to 3.4 Noun Clauses: Turning Whole Ideas into Nouns

3.5 — Relative Clauses. Clauses that act like adjectives, describing a noun with who, which, or that. → Go to 3.5 Relative Clauses: Who, Which, and That

3.6 — Conditional Clauses. The "if…, then…" family — a special case of adverbial clause that earns its own room because the patterns are so common. → Go to 3.6 Conditional Clauses: If, Unless, and In Case

Pro-Tip: If you're not sure which door to open, start with main vs subordinate (3.1–3.2). Most "is this even a proper sentence?" problems live there. Only once that's solid does it make sense to branch into what job the subordinate clause is doing.

Common Mistake: Don't treat conditionals as some separate species of grammar. They're clauses too — just wearing an "if/unless/as long as" hat. Sort your main-vs-subordinate thinking out first, and conditionals stop looking so strange.

UK vs US Note

This whole cluster shares the same grammar in UK and US English — the split between main and subordinate clauses, and the jobs those subordinate clauses do, don't change on either side of the Atlantic. The only differences you'll meet are in spelling here and there (colour [US: color]) and the odd style preference, which get flagged in the deep-dive articles as they come up. No separate rulebook to learn.

Key Takeaways

• This page is a map, not a lesson — the teaching lives in the linked articles.
• Start with the fork between main and subordinate clauses (3.1–3.2).
• Then sort subordinate clauses by job: adverbial, noun, or relative (3.3–3.5).
• Conditional clauses (3.6) are a focused subset of adverbial clauses, worth a visit once adverbials feel settled.
• If you're counting or combining clauses rather than naming their type, that's 2.1 Sentence Types, back in Pillar 2.
