How to Choose Which Language to Learn (Without Regretting It Later)

The Short Answer: Choose the Language You'll Actually Keep Studying
The best language to learn is the one you have a concrete, personal reason to use and enough real exposure to stay motivated for months. Difficulty and "usefulness" rankings matter far less than most people think, because the language you quit at week six teaches you nothing, no matter how strategic it looked on paper.
That single idea should override almost every other consideration below. A slightly "harder" language you care about will beat an "easy," practical language you feel nothing for, every time. Motivation is the fuel that carries you through the long, unglamorous middle of learning, and no spreadsheet of speaker counts can manufacture it.
So the real question isn't "what is the best language to learn?" It's "which language will I still be studying next spring?" This guide gives you a framework to answer that honestly, weigh the trade-offs, and commit without the nagging fear you picked wrong.
Start With Your Reason, Not the Language
Before you compare options, get specific about why you want to learn at all. Vague goals ("it'd be cool to be bilingual") collapse the first time studying feels like work. Concrete reasons survive.
Ask yourself which of these actually describes you:
- Connection — a partner, family, in-laws, or heritage you want to reclaim.
- Travel — a specific country or region you visit or plan to move to.
- Work — a language that opens real doors in your industry or market.
- Culture — films, music, literature, anime, or games you love in the original.
- Cognitive challenge — you simply enjoy the puzzle of a new system.
Your reason shapes everything downstream: how much speaking you need, whether reading matters, and how tolerant you can be of a slow start. Someone learning Japanese for anime can happily spend months on input before speaking. Someone learning Spanish to talk to new in-laws next month needs conversation from day one. Same advice, opposite priorities.
If more than one reason applies, rank them. The top one is your tiebreaker whenever two languages look otherwise equal.
The Five Factors That Actually Matter
Once your reason is clear, weigh candidate languages against these five factors. Notice that raw difficulty is only one of five, not the whole decision.
1. Personal connection and motivation
Weight this highest. This is your honest gut answer to "do I actually want to live inside this language?" If a language gives you a small thrill, that emotional pull is worth more than any objective advantage. Discount nothing here, and don't talk yourself into a "sensible" choice you feel nothing for.
2. Difficulty for English speakers
Languages are not equally hard for English speakers, and pretending otherwise sets you up for frustration. The U.S. Foreign Service Institute (FSI) groups languages by roughly how many classroom hours its diplomats need to reach professional working proficiency. It's a rough guide, not gospel, but it's the most-cited honest benchmark available.
| FSI category | Approx. hours to proficiency | Example languages |
|---|---|---|
| Category I | ~600–750 | Spanish, French, Italian, Portuguese, Dutch |
| Category II | ~900 | German, Indonesian, Swahili |
| Category III | ~1,100 | Russian, Greek, Hindi, Vietnamese, Turkish |
| Category IV (hardest) | ~2,200 | Arabic, Mandarin, Japanese, Korean |
These hours assume structured, full-time study, so your real timeline as a part-time self-learner will be longer and highly variable. Treat the categories as relative difficulty, not a promise. For a deeper breakdown, see our guides to the easiest languages to learn and the hardest languages for English speakers.
Difficulty shouldn't veto a language you love. It should just set your expectations so you don't quit Mandarin at month three thinking you failed, when you were exactly on schedule.
3. Resources available
A language is only as learnable as its materials. Spanish, French, German, and Japanese have oceans of apps, podcasts, graded readers, tutors, and comprehensible-input videos. A less-common language might have one decent textbook and a thin YouTube presence, which quietly makes it much harder regardless of its FSI category.
Before committing, spend twenty minutes checking:
- Are there beginner podcasts or YouTube channels you'd enjoy?
- Can you find affordable tutors (on platforms like iTalki) for conversation?
- Are there films, shows, or books you actually want to consume?
- Is there a spaced-repetition deck or app support for it?
If the answer is "barely," you can still learn it, but go in knowing you'll build more of your own path.
4. Opportunities to use it
Motivation dies without contact. The ideal language shows up in your real life: neighbors who speak it, a city you visit yearly, a workplace, an online community, a hobby. Passive "someday" usefulness is far weaker than a group chat you're in this week. Prioritize a language you can touch, not one that merely looks good on a résumé you'll never test.
If nothing in your daily life uses the language yet, you can manufacture contact deliberately: join an online community around it, follow creators, or schedule a weekly tutor call so there's always a next conversation on the calendar. But it's easier to lean on exposure that already exists than to build it from scratch, so give real weight to languages already circulating around you.
5. Time and goals
Be realistic about your bandwidth. If you have 20 focused minutes a day, a Category IV language will take years to reach conversation, and that's fine if you're at peace with the pace. If you want a usable travel language in six months, a Category I option is the sane choice. Match the language's demands to the goals you can actually commit to.
A Simple Scoring Method
If you're torn between two or three candidates, make the trade-offs visible instead of looping in your head. Score each language from 1 to 5 on the five factors, then weight motivation double because it does the most work.
| Factor | Weight | Language A | Language B |
|---|---|---|---|
| Personal connection | ×2 | ||
| Easy difficulty (5 = easiest) | ×1 | ||
| Resources available | ×1 | ||
| Chances to use it | ×1 | ||
| Fits my time/goals | ×1 | ||
| Weighted total |
Fill it in honestly and a winner usually emerges. But here's the real trick: if the "loser" leaves you disappointed, that feeling is data. It means your gut wants the other language, and you should probably follow it. The chart exists to surface your intuition, not to overrule it.
Common Mistakes When Choosing
A few predictable traps derail beginners before they even start:
- Choosing by speaker count. Mandarin has over a billion speakers, but that statistic won't tutor you at 9 p.m. What matters is speakers in your life, not the global total.
- Optimizing for "usefulness" you'll never cash in. A "practical" language you have no contact with is less useful than a "frivolous" one you engage with daily.
- Picking the easiest language purely to feel fast. Speed feels great until boredom sets in. An easy language you don't care about still gets abandoned.
- Trying to learn several at once. As a beginner, split focus means slow progress on all fronts and faster burnout. Commit to one first.
- Endless research instead of starting. The comparison itself becomes procrastination. A "good enough" choice you start today beats the perfect choice you keep deferring.
What If You Truly Can't Decide?
Sometimes two languages are genuinely tied. When that happens, use these tiebreakers in order:
- Which one can you use this week? Real contact wins.
- Which has better beginner resources? Momentum in the first month is fragile; make it easy on yourself.
- Which one, imagining yourself speaking it in a year, makes you smile more? Trust that answer.
And remember: this decision is not permanent. Skills like study habits, an ear for grammar, and memorization technique carry over between languages. Time on a language you later switch away from is never wasted, so the cost of "choosing wrong" is far smaller than the paralysis suggests.
Still Weighing Two Specific Languages?
If your shortlist has come down to the two most common beginner picks, our head-to-head on Spanish vs French walks through pronunciation, grammar, and where each is genuinely useful. Once you've committed, don't stall: turn the decision into a plan with our guides on how to start learning a language and setting goals you'll actually reach.
The languages you'll regret are the ones you never really started. Pick the one that pulls at you, give it an honest three months, and let momentum do the rest.
