English Grammar tutors, lessons & classes

English grammar is the engine room of the language, and the room most ESL programs visit too briefly. The visible product is fluency. The structural cause of fluency is grammar that has been internalized to the point of automaticity. Most adult learners who plateau at the upper-intermediate or advanced threshold can name the rule when asked but cannot deploy it consistently under conversational pressure, which is a different skill and one that grammar-focused lessons explicitly build. The students who book this specialty fall into a few clear groups: ESL adults preparing for a high-stakes test (TOEFL, IELTS, Cambridge English) where the writing rubric scores grammatical range and accuracy explicitly; native English speakers (often writers, lawyers, or graduate students) sharpening their own grammar for professional writing; teachers and tutors of English needing pedagogical command of structures they speak intuitively but have never analyzed; and curious learners working through the language as a system rather than as a survival tool. The curriculum calibrates to all four.

The English tense system is the first place most learners need real work. The conventional accounting lists 12 tenses across four time frames (past, present, future, present-perfect-as-anchor) and three aspects (simple, continuous, perfect). Present simple (I work) describes habits and general truths. Present continuous (I am working) describes actions in progress. Present perfect (I have worked) connects past action to present relevance and is the single most error-prone tense for speakers of Spanish, Italian, French, German, and most Slavic and Asian languages, because their first languages distribute the past-time semantic load differently. Present perfect continuous (I have been working) adds duration to that connection. Past simple (I worked) describes completed past action. Past continuous (I was working) describes past action in progress, often interrupted. Past perfect (I had worked) describes action completed before another past action. Past perfect continuous (I had been working) adds duration. Future simple (I will work) and the alternative going-to future (I am going to work) describe upcoming action. Future continuous (I will be working) describes future action in progress. Future perfect (I will have worked) describes action completed before a future point. Future perfect continuous (I will have been working) closes the system. A grammar-focused course works through all twelve in sequence with form, meaning, and use for each, because the famous "I have worked here since 2020" versus "I work here since 2020" error is not really a tense error but a present-perfect-meaning error that the past simple cannot perform.

Articles are the second great battleground, and the one most non-Indo-European-language speakers find genuinely difficult. English articles come in three flavors: indefinite (a, an), definite (the), and zero (no article). The basic rule is familiar (a/an for one of many, the for the specific one both speakers know about, no article for general or uncountable nouns) but the exceptions multiply quickly. The with superlatives (the tallest, the most expensive, the best). The with unique-in-context entities (the sun, the moon, the internet, the president). The with rivers, oceans, and mountain ranges (the Nile, the Pacific, the Andes) but not with individual mountains (Mount Everest) or lakes (Lake Victoria). Zero article with most countries (Italy, Japan) but the with country names containing common nouns (the United States, the United Kingdom, the Philippines, the Netherlands). Zero article with meals (breakfast, lunch) but a with a meal as an event (a quick lunch, a wonderful breakfast). The exceptions resist memorization and yield only to high-volume exposure. Lessons drill them in context for as long as the student needs.

The gerund-versus-infinitive distinction is the third high-leverage grammar topic, and one that almost every adult learner has to revisit at multiple points in their study. Some verbs take a gerund (enjoy + ing, finish + ing, avoid + ing, consider + ing, suggest + ing, practice + ing, postpone + ing, mind + ing). Some verbs take an infinitive (want + to + infinitive, need + to, decide + to, plan + to, hope + to, agree + to, refuse + to, promise + to). Some verbs take either with no real change in meaning (like, love, hate, start, begin). And a small but treacherous category takes either with a real change in meaning (stop smoking versus stop to smoke, remember to call versus remember calling, regret telling versus regret to tell). Native speakers internalize the patterns by ear and cannot usually state the rule. ESL learners need both the rule and the input. A grammar tutor builds the lists and drills them with practice that catches the easy mistakes before they fossilize.

Subject-verb agreement is structurally simple in English compared to Spanish or Italian (just one ending change, the third-person singular -s in the present tense) but produces a surprising amount of error in three specific contexts: with collective nouns (the team is winning, US convention; the team are winning, UK convention), with there + be + plural-or-singular subject (there is a problem, there are problems), and with complex subject phrases where the head noun is buried (the box of books is on the table, not are). These are the agreement errors that even fluent non-native speakers carry for years. Lessons drill the rules with the specific structures most likely to produce error in your writing or speech.

Modal verbs are their own subsystem worth explicit time: can, could, may, might, shall, should, will, would, must, ought to, plus the semi-modals have to, need to, be supposed to, be able to. Each modal carries a different load of obligation, possibility, permission, ability, advice, or prediction, and the past-tense forms (could, might, would, should have done) get used for both genuine past time and as polite or hypothetical present-time softeners (Could you help me? is a present request despite the past-tense form). Beginner courses skim modals; an honest grammar course returns to them at upper-intermediate and advanced levels because the nuance is where fluent speakers actually live.

The passive voice, the conditional system (zero, first, second, third, mixed), reported speech and the backshifting rules, relative clauses (defining and non-defining, with the famous that-versus-which distinction in American versus British conventions), the gerund-and-infinitive complement system, phrasal verbs as a grammatical category rather than just as vocabulary, the punctuation conventions that differ between American and British English (Oxford comma, single-versus-double quotation marks, punctuation inside versus outside the closing quote), the spelling and morphology rules that govern the famous double-consonant decisions (stop → stopped but visit → visited), the irregular plural patterns inherited from Old English (foot/feet, mouse/mice, child/children) and from borrowed words (criterion/criteria, phenomenon/phenomena, datum/data) — each of these gets its own lesson or sequence of lessons in a serious grammar program. None of them have to be mastered in the first month. All of them have to be addressed at some point if your writing or your test score is going to reach the upper-intermediate or advanced bands.

A few honest tutor observations on patterns we see in adult grammar learners. Memorizing the rule is the easy part; producing under pressure is the hard part. Many students arrive having read excellent grammar books from cover to cover, often the Murphy English Grammar in Use series or the Azar references, and can recite the rules on demand. The same students will skip the in front of United States in casual speech, or use the past simple where the present perfect is required. The fix is not more rules. It is hundreds of repetitions in low-stakes practice, with the tutor catching errors at the natural correction window rather than at the textbook one. Closely related: many adults plateau at upper-intermediate precisely because they have stopped learning grammar consciously and started relying on whatever sounds right. That instinct is mostly correct, which is what makes the residual 5% of errors so durable. Targeted grammar work at this level surfaces the specific patterns that the ear no longer flags. Our Cambridge English, IELTS, and TOEFL prep pages cover the test-rubric piece for students whose grammar goal is tied to a specific exam, and our conversational English and Business English pages cover the broader registers grammar sits inside.

Lessons calibrate to your level, your goal, and your specific gaps. A B2 student preparing for IELTS Writing needs deep work on the conditional system, the article system, and the present-perfect-versus-past-simple distinction because the rubric scores these explicitly. A C1 writer polishing prose for a US graduate application needs subject-verb agreement edge cases, punctuation conventions, and the gerund-infinitive distinction. A native English-speaking teacher preparing for a CELTA or TESOL credential needs pedagogical command of structures she speaks intuitively. We do not run a generic grammar course. The trial starts with you naming the goal, the tutor running a short diagnostic to find the actual gaps, and a written plan for the next four weeks. The Strommen English grammar roster includes native speakers with CELTA or DELTA credentials, several former ESL classroom teachers, a few academic writers and editors who specialize in writing-rubric coaching, and tutors who have prepped hundreds of students through Cambridge, IELTS, and TOEFL grammar sections.
