Gas
Perfect Cognate
Both come from Dutch 'gas', coined by chemist Jan Baptist van Helmont as an alteration of Latin 'chaos' (from Greek 'khaos'), originally referring to a void or formless state.
The word "gas" refers to a state of matter consisting of particles with neither a defined shape nor a defined volume that expand indefinitely to fill any available container.
The car needs more gas.
English and Spanish share thousands of words because both languages have deep roots in Latin. Over centuries, English borrowed many Latin‑based words, while Spanish evolved directly from Latin. That’s why so many Spanish words look familiar to English speakers, and vice versa.
“If you speak English, you already know thousands of Spanish words.”

Both languages inherited thousands of words from Latin — English through the Norman Conquest and centuries of scholarly borrowing, Spanish as a direct descendant of Vulgar Latin. The result is an enormous pool of shared vocabulary that makes Spanish one of the most accessible languages for English speakers.

A cognate shares a common ancestor in two languages — both words evolved naturally from the same root. A loan word is borrowed directly from one language into another. For example, "animal" is a cognate (both come from Latin), while "kindergarten" is a loan word borrowed into English from German.
Absolutely. Research shows cognates can help you pick up more vocabulary faster. Because you already know the shape and meaning, you can focus your energy on pronunciation, grammar, and the words that don't have English equivalents.
No. Perfect cognates have identical spelling (like "animal"), but most have small, predictable differences that follow consistent patterns — English -tion becomes Spanish -ción, -ity becomes -idad, and so on. Once you learn a few patterns, you can decode thousands of words.
Estimates range from 10,000 to 15,000 cognate pairs. Even a beginner can recognize several thousand Spanish words on sight, providing a significant head start in reading comprehension and vocabulary building.
