Summary
Highlights
Certain words like 'senior,' 'junior,' 'prefer,' 'prior,' 'superior,' 'inferior,' and 'preferable' are always followed by 'to' (e.g., 'he is senior to me'). In other comparative cases, 'than' is used (e.g., 'he's better than me').
'In' is used for a static location (e.g., 'sitting in the classroom,' 'in the house'). 'Into' implies movement towards or entering an enclosed space (e.g., 'came into my office,' 'driving into the garage').
'For' indicates a period of time (e.g., 'vlogging for five years'), while 'since' marks a starting point in time (e.g., 'blogging since 2014').
'Agree with' is used for agreement with a person or their opinion (e.g., 'I agree with you'). 'Agree to' is used for agreement with a plan, proposal, or idea (e.g., 'I agree to your proposal').
'To' is used for destination (e.g., 'going to Germany'), time (especially in British English like 'quarter to two' or 'from Monday to Friday'), comparison (e.g., 'prefer traveling to sitting at home'), a receiver of an action (e.g., 'gave my book to my follower'), and to express a reason for an action (e.g., 'came here to see you'). 'For' is used for benefits (e.g., 'for your health,' 'a gift for my friend'), periods of time (e.g., 'living in the U.S. for four years'), schedules (e.g., 'appointment for March 13th'), expressing a reason (e.g., 'fired for being late'), and purpose (e.g., 'videos for improving your English'). The distinction between 'to' and 'for' when expressing purpose or reason often depends on whether a noun ('for work') or a verb ('to work') follows.
The video highlights instances where both 'to' and 'for' can be used, but with slightly different meanings. For example, 'brought lunch to me' indicates direction, while 'brought lunch for me' emphasizes doing a favor. Similar distinctions apply to 'apologize for/to,' 'travel to/for,' 'wait for/to,' 'ask for,' 'belong to,' 'care for,' and 'prepare for.'
'At' is used for very exact, small places (e.g., 'at the door,' 'at the hospital,' 'at 13 Long Street'). 'On' is used with streets and avenues (e.g., 'on Park Avenue,' 'on Green Street'). 'In' is used with larger geographical locations like cities, towns, countries, parts of countries, and continents (e.g., 'in London,' 'in California,' 'in Africa').
'In' is used for enclosed spaces where you generally cannot stand up, like a car or taxi. 'On' is used for means of transportation where you can stand up, like a bus, plane, ship, or train. It's also used for things with surfaces or without roofs, like 'on a horse' or 'on a bike.'
'In a hospital' means you are a patient receiving treatment (e.g., 'waking up in a hospital'). 'At a hospital' means you are there for another reason, such as visiting someone or working (e.g., 'visiting my uncle at the hospital').
This section reviews fundamental parts of speech. Nouns are objects or subjects (e.g., 'cat,' 'table'). Pronouns substitute nouns to avoid repetition (e.g., 'he,' 'she,' 'it,' 'they'). Verbs express actions (e.g., 'go,' 'read'). Adjectives describe nouns or pronouns (e.g., 'old,' 'beautiful'). Adverbs describe actions, adjectives, or other adverbs, often ending in '-ly' (e.g., 'quickly,' 'slowly'), but some, like 'fast,' can be both adjective and adverb depending on usage. Prepositions modify phrases (e.g., 'about,' 'on'). Conjunctions join words or sentences (e.g., 'and,' 'but'). Articles are 'a,' 'an,' and 'the.'
English sentences generally follow a subject-verb-object structure (e.g., 'She smiled at a boy'). Adverbs describing the verb typically come before the verb (e.g., 'She briefly smiled'). Adjectives come before the noun they describe (e.g., 'a little boy'). A key rule: adverbs cannot be placed between a verb and its object (e.g., 'they play often tennis' is incorrect).
Articles are crucial in English. 'A' or 'an' (indefinite articles) are used for singular, non-specific countable nouns, especially when first mentioned (e.g., 'a mug,' 'an apple'). 'The' (definite article) is used for specific nouns that have already been mentioned or are one-of-a-kind (e.g., 'the mug,' 'the Moon,' 'the dress that you wore yesterday'). Articles are not used with uncountable nouns (e.g., 'milk,' 'information' in general), plural countable nouns (e.g., 'computers,' 'bloggers'), most proper nouns (e.g., 'New York,' 'Russia,' 'Tuesday'), languages (e.g., 'French'), or meals (e.g., 'lunch'). Exceptions exist when specificity is implied, even with these categories (e.g., 'the milk from that store').
Present Simple describes regular actions, habits, and schedules. Marker words include 'every day/week/month,' 'often,' 'seldom,' 'rarely,' 'always,' 'never,' 'sometimes,' 'as a rule,' 'hardly ever,' 'from time to time.'
Past Simple describes completed actions in the past. Marker words include 'yesterday,' 'the day before yesterday,' 'last week/month/year,' 'ago' (e.g., 'a week ago'), 'the other day,' specific past years (e.g., 'in 1994'), 'once,' 'once upon a time,' and specific times in the past (e.g., 'at three o'clock yesterday').
Future Simple (with 'will') is used for predictions or decisions made at the moment of speaking, or when there's an element of uncertainty. Marker words include 'tomorrow,' 'the day after tomorrow,' 'next week/month/year,' 'in an hour/second/minute,' 'soon,' 'later,' 'someday,' 'in a day/week/five years,' 'in the future,' 'one of these days.' For scheduled events that are 100% certain, Present Simple is often used (e.g., 'the plane arrives at 5 PM').
Present Progressive describes actions happening right now or around the present. Marker words include 'now,' 'right now,' 'at the moment,' 'today,' 'look!', 'listen!', 'still,' 'at this very moment,' 'currently,' 'these days,' 'this week/month/year,' 'constantly.'
Present Perfect focuses on the result of a past action on the present, not the exact timing of the action. Marker words include 'ever,' 'never,' 'since,' 'already,' 'yet,' 'recently,' 'lately,' 'before,' 'always,' 'so far,' 'at last,' 'it's the first/second time,' 'all my life,' 'all morning/day.' It's crucial not to confuse it with Past Simple, which details specific past events. Present Perfect often indicates life experiences (e.g., 'I've been to the UK') or actions within an unfinished time frame (e.g., 'this year,' 'today'). The structure is 'have/has' + past participle (third form of the verb). For formal contexts, avoid contractions like 'I've been' and use 'I have been.'
'On' and 'upon' are interchangeable, but 'upon' is more formal and old-fashioned, often found in fairy tales (e.g., 'once upon a time'). For everyday use, 'on' is preferred (e.g., 'put your book on the table').
The video starts by addressing the common confusion between 'at' and 'in'. 'In' is used for larger, more general locations like countries, cities, and continents (e.g., 'in Europe,' 'in Rome'). 'At' is used for smaller, more specific locations like buildings or venues (e.g., 'at the airport,' 'at the farmer's market').
The rule for 'all' vs. 'all of' is straightforward: 'all of' is used with pronouns (e.g., 'all of us,' 'all of them'), while 'all' is used in all other cases (e.g., 'all the people,' 'all the students').
When discussing time, 'in' is used for general measurements (e.g., 'in two minutes,' 'in two months,' 'in 1990'). 'On' is used for specific dates (e.g., 'on Monday,' 'on September 21st'). 'At' is used for specific times (e.g., 'at 12 pm').
'Beside' means 'nearby' (e.g., 'camping beside the river'), while 'besides' means 'in addition to' (e.g., 'besides two suitcases, I'm taking three boxes').
'Among' is used for a group of three or more objects or people (e.g., 'popular among her classmates'), whereas 'between' is used for two objects (e.g., 'decide between going to the cinema and staying home').
