FlashBoss - Spanish Core: 1,000 words, A1–A2 foundation
Fibonacci spaced repetition and boss fights.
Spanish Core is built from subtitle corpora and academic frequency lists — the Spanish people actually hear in film, television, and conversation, weighted toward what matters most for comprehension.
1,000 words across five tiers, arranged in themed clusters. Every card carries a Spanish example sentence constructed from vocabulary you already know, with full text-to-speech on the target word and sentence. By the time you've finished Core, you've read over 10,000 words of Spanish in context — and you're ready to walk into an A2 classroom with the grammar and vocabulary to follow what's happening.
In this pack:
1,000 high-frequency Spanish words
Five thematic tiers with progressive grammar introduction
Constructed example sentences — every word you read is one you've seen before
Text-to-speech on every target word and example sentence
Reference lessons pinned to key cards, covering grammar, phonology, and Latin American / Peninsular variation
Boss-fight graduation: no cluster is cleared until its hardest words are mastered
The full word list and all reference lessons for every FlashBoss pack are available on the website, along with a playable boss-fight demo.
