It would be useful, if the examples do not give phrases from other languages!
For exemple in Portuguese, I found the word ‘ta’ which was used as a short word for está. However, in the example phrases, I only found FRENCH phrases. Languages should not be mixed!
It’s strange to hear that it would be showing examples from another language. Would you be able to send over a screenshot of this (preferably the whole page) so we might get a better idea of what is happening here? You can send it to support (at) lingq.com. Thanks!
