All format details

wuDict searches all your dictionaries at once. Results are streamed as soon as they are available, so you get the first hit while the other dictionaries are still being searched.

Mode Results Available
Exact the headword itself, ignoring case and accents - corazon finds corazón always
Prefix every headword that starts with your text always
Contains your text anywhere inside a headword on-demand per dictionary
Full-text words inside the article text, ranked by relevance on-demand per dictionary

exact and prefix modes work instantly. Contains and full-text need an extra index which can be enabled on a per-dictionary basis. The ☰ panel offers each one as a switch and shows the estimated index size, e.g. 42MB.

Lemmatization (morphology) allows wudict to find understand when you search for understood, searching for estuviera will land on estar. English is built in; other languages can be installed via ☰ → ⚙️ → Lemmatization… (see also Lemmas)
