There is no grammar in this, so try to use this word-by-word.
Please note that for Litish the's and a's, the automatic translation is the generalised/ neutral form, along with other words.
For languages, you have to type in "French language". French will give you the adjective relevant to French things. To achieve nationality, type in "French person" or "Finn" "Spaniard" etc etc. Please note that only the adjective is currently available, and the country.
