If I’m over 25, is it still too late

Just stop. I don’t mean to be one of those people but you apparently have no idea how young 25 is. People have started over, gone to school, completely changed careers, moved to new countries, and yes: learned different languages in their 70’s+. It’s not too late for them, and it’s not even close to too late for you.

Children seem to have the easiest time learning a new language, but the rest of us can as well! The key is immersion. If you can converse with a native-speaker every day, you’ll probably have the most success, but whatever you do, be consistent!

Brain plasticity, window of opportunity, it’s all babble. You can learn new languages just fine as you age; the matter here is how much time you spend using the language.

The reason why adults perform generally worse than kids learning languages is mostly motivational, and not spending enough time with the language. But as an adult you got access to a bunch of resources that kids wouldn’t, such as a decent grasp of grammar on theoretical grounds, that you can (and should) use to your advantage.

Note however that watching sitcoms will likely not be enough to get any decent grasp of any language. (Otherwise I’d be speaking Japanese, given the amount of anime that I watch.) You’ll need proficiency on four levels: hearing, speaking, reading, writing.

No and no. It’s not too late, and just watching sitcons won’t teach you enough to start speaking. But if you just start actual studying and practicing you can learn it just fine. Watching TV can be used to practice listening, but on it’s own it’s not enough unless you’re a wonderkid.

I would say you probably won’t have as much success just listening to something than you would communicating back, no matter how much you immerse yourself. My spoken French is godawful, but my comprehension is good so I can follow along with tv shows and such, but my communication doesn’t improve much as there is no back and forth.

I know this is a bit of a necro-bump, but Today I Found Out just released a video answering exactly this question: https://inv.nadeko.net/watch?v=ipDdWx67H9M

I’ve learned (I guess still learning) a new language as an adult for the last 2 years. I tried just about every method to learn (classes, courses, books, god knows how many apps/services). To get to the point of being able to accelerate your learning with foreign movies & TV shows, you need to have consumed around 200-400hrs of the language in a comprehensible format first. This is how I would do it if I had to again:

• Forget about grammar for now. Grammar is boring and it will make you second-guess when trying to form sentences. Better to just practice and have someone correct you as needed. You’ll learn grammar naturally to an extent (i.e. it will just SOUND right), and you can supplement it later on when you have a better grasp of the language.
• Use beginner audio lessons that focus on simple phrases and/or short stories (e.g. Pimsleur or US foreign service language tapes). This is to help train your ear to understand how words are pronounced. This should get you about 40-50hrs of practice.
• Find some French youtubers that use the comprehensible input (Krashen) method to complement the audio course - some recommendations in this reddit thread
• Once you have around 50-100hrs in, now is the time to find some easy content to consume. My recommendations would be: 1) movies/tv shows you already watched in english but dubbed in french (so you already know the context. You might need to leave off french subtitles if they don’t match audio), 2) podcasts or audiobooks where only one person speaks at a time, 3) french kids shows
• After 100hrs, I would continue to consume content as detailed above but you might be able to throw in some easy french-made movies/shows at this point - your goal is to understand about 80%. If you find you can’t understand enough, put it on the backburner to revisit later. You might also be able to read an easy french book now too. You could just reread a book you’ve already read in English but translated in French now (again, so you have context; I read Harry Potter for instance)

Learning a new language at an older age was pretty eye-opening. It’s definitely harder than I expected but it’s so rewarding to be able to connect with a different group of people at a much deeper level, as you also start to understand their culture a lot more, and it gives you access to new movies, shows, theatre, books, music etc. etc.

Good luck on your journey and let me know if you have any Qs!

It’s never too late to learn a language but it’s a bit of an uphill battle, and you’re not going to learn it by just watching shows. You need to practice regularly and understand the grammar and sentence structure. You also have to speak it with other people to get feedback, you can’t only learn to listen.

It’s never too late to learn a language. However, French is one hell of a step coming from English.

French is my main language and even if I’ve been speaking it for close to 40 years now, I still learn language exceptions and rules today.

Still, I’d give it a go if I were you, learning something new is always fun. Enjoy!

Irrelevant: French is a waste of time.

I work for the Federal Government of Canada, and for reasons that are hopefully obvious, it’s important that they are able to have a pipeline that teaches French to people over the age of 25 in about a year. It’s not as simple as just watching media though. The French training for public servants starting at 0 French is a full-time job. People literally disappear from their jobs for a year or more in order to learn French.
