A dictionary. Not a translator.
Glossema defines one word, in the sentence where you met it. It is simple, it is fast, and it is meant to stay that way. It is also a way to hold on to the words you stumbled over.
What it is.
A multilingual dictionary
French, English, Spanish. The word can be in one language and its definition in another: read in English, understand in French.
Contextual
The sentence around the word is read with it. What comes back is the sense used there, not the list of the eleven others.
Fast
Point, tap the word, read. A few seconds, without leaving the page you were holding.
A way to remember
The words you look up are filed by what you were reading, and come back to you at spaced intervals. What you stumbled over once ends up yours.
Open to try
Nothing to create in order to try: the first lookups need no account.
What it is not.
A text translator
Glossema works at the level of the word, in its sentence. A whole page or a document is another trade.
An encyclopaedic dictionary
No illustrated plates, no developed etymology, no literary citations: an entry goes to the meaning, and stops there.
A long answer
A definition runs to a few lines: long enough to understand, not long enough to settle in.
A language course
No exercises, no grammar, no conjugation: what you retain, you retain from your reading.
It all comes down to speed
A definition that arrives in two seconds gives you back your page; the same one, three screens down, takes you away from it. That is why an entry stays short: light enough to consult ten times in a chapter without the reading stopping.
If you want something else
To translate a paragraph, translators do that very well. For etymology, attestations and citations, Wiktionary — from which Glossema draws part of its material — is more complete, and free. Glossema, for its part, serves the moment you stumble on a word and want to get back to your line.
