Latin Pattern Dictionary

Recognizing how Romance languages connect through shared words.

Explore how Romance languages are connected through shared words. The Latin Pattern Dictionary is an experimental reference that helps learners recognize patterns across Spanish, French, Italian, Portuguese, and their Latin roots.

What it is?

Latin Pattern Dictionary is a searchable reference of words that are 95–100% similar across Romance languages.

Instead of studying each language in isolation, the app organizes related words side by side, making similarities easier to recognize and explore.
