Question 1

How many Spanish words do I need to know to be fluent?

Accepted Answer

For basic conversational fluency, you need around 2,000-3,000 words (B1 level). For comfortable fluency in most situations, aim for 5,000-8,000 words (B2 level). Native speakers typically know 20,000-35,000 words, but you don't need that many to communicate effectively.

Question 2

How accurate is this vocabulary size test?

Accepted Answer

This test uses word frequency sampling to estimate your vocabulary size. It tests words from different frequency bands (common to rare) and extrapolates your total vocabulary. While not perfectly precise, it gives a reliable estimate within a reasonable range.

Question 3

What vocabulary size corresponds to each CEFR level?

Accepted Answer

Approximate vocabulary sizes by CEFR level: A1 (500-1,000 words), A2 (1,000-2,000 words), B1 (2,000-4,000 words), B2 (4,000-8,000 words), C1 (8,000-16,000 words), C2 (16,000+ words). These are estimates as CEFR focuses on communicative ability, not just vocabulary count.

Question 4

How can I improve my Spanish vocabulary?

Accepted Answer

The best ways to expand vocabulary are: (1) Read extensively in Spanish - news, books, subtitles, (2) Use spaced repetition systems like flashcards, (3) Learn words in context through sentences, not isolation, (4) Focus on high-frequency words first, (5) Practice actively by writing and speaking.
