how are we supposed to know if it is independant or independante in this case?
From an audio exercise, you must use the feminine form because you will hear the final T pronounced. In the masculine form, the final T is silent. This is generally true of all adjectives and nouns that end in "e" in their feminine form, e.g., avocat/avocate, grand/grande.
But the voice is so clearly masculine, I never gave the feminine form any consideration.
Unfortunately, one of the "features" of Duolingo is that the male and female voices used in the text-to-speech mode are not related to what the sentence actually says. I.e., unlike other learning sites, Duo's voice is not a clue; you must listen to the pronunciation of the words.
Exactly. Other examples: avocat (m), avocate (f), grand (m), grande (f).
Is there a difference between: "I have to be independent" and "I have to become independent"?
In this context, why is "to be" the preferred translation here? Thanks in advance!
how about saying i must be independent; is it true or no ? Thanks for answering me.
Is there a reason 'separate' (instead of 'independent)', is wrong?
I am separate (?) may be grammatical but it is not the natural choice. You could say "separate" about a room (Tu es dans une chambre indépendante) or an entrance (Tu peux utiliser l'entrée indépendante), but it doesn't fit with a person.
I don't hear the "s" of dois: it sounds as " je duà etre" instead of "je duas etre". Is this right?
Learning about liaisons in spoken French is one of the best things you can do to improve your ability to speak French at different levels of formality. There are some liaisons that are required and some are forbidden. Learn these first. Then there are others that are optional. There are far too many rules about liaisons to list here but here is a link to a very complete source. http://french.about.com/library/pronunciation/bl-liaisons.htm The case of "Je dois être...." falls in the category of an "optional" liaison, so you may choose to ignore it (more informal) or use it (perhaps a bit more elegant French).
I'm confused about the pronunciation of "s" at the end of a word. For example, I can hear it is pronounced in "Tu as un trou dans ta chaussure." So, I thought it should be always pronounced if the next word starts with a vowel, but in the case of "dois être" it seems silent. Where's the difference?
The last letter is only pronounced if a vowel is following, t.ex. In your example "tu as un trou..." the -s is followed by the vowel u of un. The same goes if a word ends on -e like the female word independente. On the other hand it is usually not done with être which has no simple vowel but a circumflex on it. I guess this makes the difference though it might not be wrong to bind them together?
It's not about ê vs. e, it is that this particular liaison is optional. It is often omitted in everyday speech. But using the liaison is a sign that you have learned to speak a somewhat more refined level of French. http://french.about.com/library/pronunciation/bl-liaisons-o.htm
I read that liaision (pardon the spelling) of the consonant in verbs (so saying dois zêtre) is very uncommon except in very very posh French and to use it in normal conversation would sound about as normal as the word "thou" in English
The "s" in "dois" followed by a vowel or mute H involves an optional liaison. See the link above.
