Topics are grouped so that earlier sections lay groundwork for later ones — but every lesson is fully self-contained and can be studied on its own. Follow the order for the most logical progression, or jump straight to whatever you need.
1
Foundations
Core topics that appear in virtually every sentence of English. A solid grasp of verb tenses, articles, nouns and the words that introduce them underpins everything else on this site — and rewards study at any level.
Tenses
Verb Tenses & Their Functions
Why do we use the present perfect instead of the past simple? Learn the function behind all 12 major tenses — not just the form.
Articles
Articles: a, an & the
Master when to use the indefinite article, the definite article, or no article at all — including geographic names and tricky special cases.
Prepositions
Prepositions
Learn the rules for in, on and at for both time and place, master movement prepositions, and build a bank of fixed verb and adjective phrases.
Nouns
Countable & Uncountable Nouns
Understand which nouns can be counted and which cannot — and master the quantifiers, partitive expressions and common exceptions that follow from that distinction.
Determiners
Determiners
Master each, every, all, both, either, neither, some and any — the words that tell us which one and how many, with clear guidance on the differences that catch learners out.
2
Sentence Building
Learn what a well-formed sentence looks like, how to compare and connect ideas, and how to recognise and fix the most common errors. These lessons build the structural awareness needed for the clause work in Section 3.
Structure
Sentence Structure
Master simple, compound, complex and compound-complex sentences — and understand the difference between independent and dependent clauses.
Problems & Style
Sentence Problems & Parallelism
Spot and fix fragments, run-ons, comma splices, choppy and stringy sentences — plus master parallel structure in lists and comparisons.
Comparison
Comparatives & Superlatives
Learn to form and use comparatives and superlatives correctly — including spelling rules, irregular forms, the more…the more, as…as, and one of the most…
Linking Words
Linking Words & Discourse Markers
Master the words that hold writing together — adding, contrasting, giving reasons, showing results, sequencing and summing up — including the clause vs noun distinction for despite and although.
3
Subordinate Clauses
Three types of dependent clause, each adding a different dimension to a sentence. Adverb clauses are the most familiar starting point; noun clauses the most abstract. The order here makes a real difference.
Clauses
Adverb Clauses
Add detail about when, why, how and conditions using connector words like because, although, when and if.
Clauses
Adjective Clauses
Describe people, places and things using who, which, that, whose, where and when — and master the comma rule.
Clauses
Noun Clauses
Use an entire idea as a single noun — as the subject, object or complement of a sentence — with that, what, whether and more.
4
Advanced Structures
Six topics where a solid background in verb forms genuinely helps. Each centres on a particular way English reshapes or extends the verb — and each is fully self-contained.
Phrases
Participles & Participial Phrases
Turn verbs into vivid descriptions using -ing and -ed forms — and learn to avoid the dangling participle.
Voice
The Passive Voice
Shift the focus from the doer to the action across all tenses — and know when the passive is the right stylistic choice.
Conditionals
The Conditionals
Master zero, first, second and third conditionals — from always-true facts to impossible past scenarios — and explore modal variations.
Modal Verbs
Modal Verbs
Master can, could, may, might, must, should, ought to and more — and understand the six functions they express: ability, permission, obligation, deduction, possibility and advice.
Verb Forms
Gerunds & Infinitives
Learn which verbs take -ing, which take to + verb, and which take both — including the pairs where the choice changes the meaning entirely, such as stop smoking vs stop to smoke.
Reported Speech
Reported Speech
Learn to report what someone said, asked or commanded — with clear guidance on how tenses move back, which words change, and how say differs from tell.
