What is the Best Language to Learn for English Speakers?

For most English speakers, Spanish is the best language to learn because it balances high utility, linguistic similarity, and accessible resources. According to data from the Foreign Service Institute (FSI), Spanish is a Category I language, meaning it takes roughly 600-750 class hours to reach professional proficiency. However, the “best” choice depends on your specific goals, whether you are seeking career advancement, easier travel, or cognitive development.

What is the Best Language to Learn for English Speakers?

In my decade of testing language-learning platforms like Duolingo, Babbel, and Pimsleur, I’ve found that the best language is the one you will actually use. While Mandarin Chinese offers massive economic potential, the high barrier to entry (tones and characters) often leads to burnout. Conversely, Spanish or Norwegian provide “quick wins” that keep your motivation high through the difficult intermediate plateau.

Quick Takeaways: Choosing Your New Language

  • Most Practical: Spanish (due to over 500 million speakers and high US/UK relevance).
  • Highest ROI (Economy): Mandarin Chinese (essential for global trade and tech sectors).
  • Easiest to Master: Norwegian or Dutch (closest grammar and vocabulary to English).
  • Best for Diplomacy: French (the official language of the United Nations and Olympic Games).
  • Long-Term Strategy: Choose a language based on your social circle or travel plans to ensure consistent practice.

Top 5 Languages Ranked by Utility and Ease

When determining what is the best language to learn for English speakers, we must look at the Return on Investment (ROI). This includes how much effort you put in versus how much “utility” (career, travel, and social access) you get back.

Why Spanish is Consistently the Best Language to Learn for English Speakers

If you live in North America or Europe, Spanish is almost always the logical choice. It is the second most spoken language in the world by native speakers. This means you have a nearly infinite supply of movies, podcasts, and native speakers to practice with.

One of the biggest advantages is phonetic consistency. In Spanish, words are almost always pronounced exactly as they are spelled. Unlike English, where “tough,” “through,” and “though” all sound different, Spanish vowels are stable and predictable.

Furthermore, English and Spanish share thousands of cognates. These are words that look and sound similar and have the same meaning, such as “hospital,” “actor,” and “original.” During my first trip to Mexico City, I realized I already knew roughly 20% of the vocabulary just by being an English speaker.

The Economic Case for Mandarin Chinese

While it is significantly harder to master, Mandarin Chinese is often cited as the best language for professionals. China is the world’s second-largest economy, and being able to negotiate without a translator is a high-income skill.

Mandarin is a tonal language, meaning the pitch of your voice changes the meaning of a word. For example, the word “ma” can mean mother, horse, hemp, or a scold, depending on the tone.

While the logographic writing system (characters) requires thousands of hours of memorization, the grammar is surprisingly simple. There are no verb conjugations, no genders, and no plural forms. If you are looking for a challenge that sets your resume apart from the crowd, Mandarin is the clear winner.

Evaluating Difficulty: The FSI Scale for English Speakers

To understand what is the best language to learn for English speakers, we must reference the Foreign Service Institute (FSI). They rank languages based on how long it takes a native English speaker to reach “General Professional Proficiency.”

Category I: The “Easy” Languages (600-750 Hours)

These languages are linguistically close to English. If you want to see progress quickly, start here.


  • Danish

  • Dutch

  • Italian

  • Norwegian

  • Swedish

  • Spanish

  • French

Category II & III: The “Moderate” Languages (900-1100 Hours)

These have significant linguistic differences from English but share some similarities.


  • German (Category II)

  • Indonesian

  • Swahili

Category IV: The “Super-Hard” Languages (2200 Hours)

These are exceptionally difficult for native English speakers due to completely different syntax and writing systems.


  • Arabic

  • Japanese

  • Korean

  • Mandarin Chinese

How to Choose Your Target Language (A 3-Step Framework)

Choosing a language is a long-term commitment. To avoid quitting after the first month, I recommend using the Goal-Alignment Framework.

Identify Your “Why”**

Are you learning for Career, Heritage, or Adventure?


  • Career: Focus on German, Mandarin, or Japanese.

  • Adventure: Focus on Spanish, French, or Portuguese.

  • Brain Health: Focus on complex languages like Arabic or Greek to maximize cognitive plasticity.

Assess Your Resources**

Do you have access to native speakers? Learning Tagalog might be the best choice for you if your spouse’s family speaks it at home, even if it isn’t “globally dominant.” Personal connection beats global utility every time when it comes to motivation.

Test the “Melody”**

Spend 30 minutes listening to music or watching news in your top three choices. You will spend hundreds of hours listening to this language; you need to enjoy the way it sounds. I personally chose Italian over German early in my journey because the musicality of the language kept me engaged during long study sessions.

Maximizing Information Gain: Common Myths Debunked

  • Myth: “You are too old to learn a language.” Research shows that while children are better at accents, adults are more efficient at learning grammar structures and systematic vocabulary.
  • Myth: “Immersion is the only way.” You can create a “digital immersion” environment using VPNs to watch foreign Netflix or using iTalki to hire affordable tutors.
  • Myth: “English is the only language you need.” While English is a global lingua franca, learning a local language builds trust and cultural empathy that English alone cannot provide.

Frequently Asked Questions

Is it better to learn Spanish or French?

If you live in the United States, Spanish is generally better due to geographical proximity and the high number of local speakers. If you are interested in diplomacy, international law, or traveling through Africa and Quebec, French is the superior choice.

What is the fastest language for an English speaker to learn?

Norwegian and Swedish are often considered the fastest. Their grammar is remarkably similar to English, and many words are nearly identical. For example, “Will you help me?” in Norwegian is “Vil du hjelpe meg?

Does learning a second language help your career?

Yes. Studies by The Economist suggest that being bilingual can increase your lifetime earnings by 2% to 5%. In specific fields like healthcare, international sales, and customer success, the premium can be even higher.

Is Japanese harder than Mandarin?

For reading and writing, Japanese is often considered harder because it uses three different writing systems (Hiragana, Katakana, and Kanji) simultaneously. However, for speaking, Mandarin is harder due to its strict tonal system.
