Iedra

Iedra is a Spanish-language word search and exploration platform that turns the usual dictionary approach around: instead of starting with a word to find its definition, users can search from a meaning to discover words that fit. Its advanced search tools let visitors look across entries, definitions, and etymologies, and narrow results by features such as rhyme, length, syllables, grammatical category, usage frequency, subject, and linguistic origin. Users can also explore words by dictionary source, including the DLE of the Royal Spanish Academy, Moliner, Seco, and the DPD, with options to compare coverage and identify entries found in particular dictionaries.

Additional features include searches for inflected forms, fixed expressions, etymological relationships, and changes between editions of the DLE. Beyond its core word search, Iedra offers sections for rhymes, an atlas, games, and updates about its data and tools. The site presents itself as an exploratory resource for Spanish vocabulary, connecting meanings, words, dictionary references, and language history in one searchable experience
