Firefly Linguistics

Firefly Linguistics is a curated Spanish-English language resource created by Andrew Lillie, a trained linguist and translator, member of the Chickasaw Nation, and professional with more than 30 years of experience working between the two languages. Guided by the principle of filling gaps in knowledge, the site helps readers navigate specialized vocabulary and explore the connections between Spanish and English.

Its resources include bilingual glossaries for fields that may be overlooked by major publishers, such as culinary arts, chocolate making, kitchen equipment, edible flowers, and blood donation terminology. Visitors can also browse Spanish vocabulary lists organized by subject, spanning areas such as architecture, law, medicine, science, finance, culture, and technology. Articles explore language, etymology, Spanish dictionaries, and topics that illuminate the space between the two languages. Firefly Linguistics also curates Spanish-language dictionaries and other reference tools, selected through the perspective of a working language professional. Together, its glossaries, articles, and recommended resources serve translators, language learners, professionals, and anyone seeking practical Spanish-English knowledge.
