Spanish wordlists (priv/wordlists/)

spanish.txt — 50k base list

The 50,000-word Spanish frequency list at priv/wordlists/spanish.txt is the 2018/es/es_50k.txt file from hermitdave/FrequencyWords (MIT License, © Hermit Dave), with the per-line frequency column removed so only the lowercase word survives. The frequencies are themselves derived from the OpenSubtitles 2018 corpus.

spanish_mx_extras.txt — Mexican legal/fiscal vocabulary

Project-specific supplementary wordlist (~700 entries) curated for Mexican tax-document extraction. Contains SAT terminology, common labour/employment terms, document/process vocabulary, adverbs and verb conjugations not present in the subtitle-derived 50k list.
