Consuming all kinds of media in a wide range of topics is a solid way to increase your chances of encountering new vocabulary. Fiction or non-fiction, written or visual or auditory, doesn't matter. All roads lead to Rome. Reading novels and watching documentaries are also lots of fun, so double benefit. Hanging out in English speaking social media platforms is a pretty good way. Most people improve their language purely by exposure to social media. You could also solve crossword puzzles, that way you can learn more synonyms/antonyms.


Leaving your comfort zone and learning new stuff. Not just academic material. I see where is simonthemooncat coming from, but this is a common mistake of the natives. Most advanced learners are just fine with academic language (even though there is always new stuff to learn) but less comfortable with the very informal language, with details of the daily life, with emotional expressions and nuances in the language. Don't make the mistake of learning just lists of idioms and books for university students. Nope. Work also on expressing your funny stories better, on joking in a way that suits your personality, watch something that reflects how teens speak, or how people from various regions speak, and so on. Be more and more yourself in a new language and culture. For that, you need to learn more of both the "high" and the "low" stuff.


Yeah, I wouldn't suggest just reading academic stuff either. I am about where OP is in English, but in Spanish. I could learn and study academic literature all day long. Sometimes I do for sheer curiosity. But that's not gonna help you at a cocktail party. In practice, knowing the difference between words like intrinsic and inherent doesn't matter worth shit. Natives don't speak like academic papers in any language. It's much more useful to see how people speak casually. Maybe learn phrases that aren't universal. Consume lots of media. I feel like once you're officially advanced, you're well beyond the "study and educate yourself" phase and more into the, "actually use the language and learn that way" phase


My advice would actually be to read fiction. Find genres you like, and read - a lot. I've read thousands of English books, tens of millions of words, and I used to encounter words or phrases that were unfamiliar to me regularly. It still happens, but these days it's maybe once a year...


Input, input, input. Vary your input (e.g. textbooks, various fiction genres, modern books, older books, same for movies, documentaries, shows...), search out stuff that's in your fields of interest as that terminology will be most useful for you.


Keep reading normal novels. Most people on here who have reached C1 say they still encounter plenty of new words in books, and several posts have talked about how reading a certain number of pages got them from C1 to C2. Pretty sure it’s a myth that there’s nothing for you but academic texts at C1.


Read some high-brow periodicals, such as *The Atlantic* or *The Economist*, or even *The New York Review of Books*.


+1 for The Atlantic - very well written, huge range of topics, and there will certainly be vocab and constructions you won’t know.


Or *The New Yorker* magazine…


what I find most helpful in this situation is reading a lot of books




My only thought is to just watch movies and read books. Try to branch out so you’re not consuming similar content


What literature have you read? e.g. read Rudyard Kipling: > They met a troop of long-haired, strong-scented Sansis with baskets of lizards and other unclean food on their backs, their lean dogs sniffing at their heels. These people kept their own side of the road, moving at a quick, furtive jog-trot, and all other castes gave them ample room; for the Sansi is deep pollution. Behind them, walking wide and stiffly across the strong shadows, the memory of his leg-irons still on him, strode one newly released from the jail; his full stomach and shiny skin to prove that the Government fed its prisoners better than most honest men could feed themselves. Kim knew that walk well, and made broad jest of it as they passed. Then an Akali, a wild-eyed, wild-haired Sikh devotee in the blue-checked clothes of his faith, with polished-steel quoits glistening on the cone of his tall blue turban, stalked past, returning from a visit to one of the independent Sikh States, where he had been singing the ancient glories of the Khalsa to College-trained princelings in top-boots and white-cord breeches. Kim was careful not to irritate that man; for the Akali’s temper is short and his arm quick. Here and there they met or were overtaken by the gaily dressed crowds of whole villages turning out to some local fair; the women, with their babes on their hips, walking behind the men, the older boys prancing on sticks of sugar-cane, dragging rude brass models of locomotives such as they sell for a halfpenny, or flashing the sun into the eyes of their betters from cheap toy mirrors. If this is too easy for you, you can read some Nabokov. He uses a more complex sentence structure and a large vocabulary and can be challenging for C1: >A sense of being late for some appointment as odiously exact as school, dinner, or bedtime added the discomfort of awkward haste to the difficulties of a quest that was grading into delirium. The foliage and the flowers, with none of the intricacies of their warp disturbed, appeared to detach themselves in one undulating body from their pale-blue background which, in its turn, lost its papery flatness and dilated in depth till the spectator's heart almost burst in response to the expansion. He could still make out through the autonomous garlands certain parts of the nursery more tenacious of life than the rest, such as the lacquered screen, the gleam of a tumbler, the brass knobs of his bedstead, but these interfered even less with the oak leaves and rich blossoms than would the reflection of an inside object in a windowpane with the outside scenery perceived through the same glass. And although the witness and victim of these phantasms was tucked up in bed, he was, in accordance with the twofold nature of his surroundings, simultaneously seated on a bench in a green and purple park. During one melting moment, he had the sensation of holding at last the key he had sought; but, coming from very far, a rustling wind, its soft volume increasing as it ruffled the rhododendrons—now blossomless, blind—confused whatever rational pattern Timofey Pnin's surroundings had once had.


Damn, these are fool of new words Probably gonna give it a try


Have fun with watching and reading whatever you want, talking with people from all kind of walks of life. That’s all ☺️ Best is probably reading though


Whatever profession you’re in or want to be in — read that. If you want to be a writer, and in English at that, read some great writers. One suggestion: read something in your native language and compare it to a good English translation of the same oeuvre.


Learn the phrase “ahhh my ass is on fire, why’d I eat all that spicy food???”


I’m sure this can be a useful phrase in many diff languages


As a native English speaker I would recommend reading academic material. Some of it may be dry but that's the only "new" challenge for C1 level. And as for idioms there's tons of books out there on lists of idioms. Just find one that catches your fancy.


And to also mention that there are new words even natives encounter daily. When you read out of your comfort zone


This is very true. I enjoy STEM academics so I don't run into new words too often anymore; but whenever I have a temporary interest in legalese I have to brush off my wife's Law Dictionary


Lots of input and lots of output. Between C1 and C2 for me it was: reading and listening to as much as a could from as many sources as I could, and writing *a lot*.


I’m a native English speaker and I’d recommend reading classic English literature. A lot of our vocabulary and phrases come specifically from these books. So not only will you be reading great literature but also you can see the language evolve as you go from book to book. I’d then recommend listening to The History of English Podcast as a supplement to reading the English classics. That way you can contextualize the English used in the book you’re reading and understand why it was written the way it was. Finally, if you’re looking to learn more colloquial English, then head over to Urban Dictionary. It’s a great resource for learning more casual words and expressions. Edit: Note that The History of English Podcast is current to just before 1600 CE. Hopefully one day it will span the entirety of the language.


Everyone is suggesting reading new material, but I'd recommend writing (and speaking) too. Active knowledge often lags behind passive knowledge, which means you likely still have a lot of progress to do writing articles, telling stories, making presentations, etc. This allows you to cement your knowledge and develop skills that the majority of people (native speakers included) are not so great at. Plus, by having someone proofread your writing, you'll be able to identify mistakes you might have never noticed you've been making.


I listen to tons of audiobooks and I've learned a lot of words that way


Have fun, and put yourself in situations where you will need to use the knowledge you want - if you want technical stuff, interact with technical people on social media. But have fun, English is easy to keep improving because THERES so much content to consume…


Consume more content and consume more advanced content. Get a degree in english. Attend or watch advanced college lectures in english- which can be found for free on youtube. Read advanced materials or technical documents in english. dive into a specific field in english.


Maybe start reading some articles in academic journals about themes that you're interested in?
