French language Q&A Forum

My dictionary offers both as a translation of teaspoon.  Only the latter was accepted in this exercise.  Is there a distinction?   In English, a teaspoon is a smaller spoon, i.e. smaller than a tablespoon, used to eat with or to stir something.  A teaspoon is also a unit of measurement.  We use the same word for both.  What about French ?  Is there a difference between petite cuillère and cuillère à café ? 

Just wondering why these exercises aren't marked automatically.   I think the whole thing would flow much better if we could go straight from one section to the next.

Is it not acceptable here to say 'Cherchez-vous'?

this combination of verb tenses in a si claus/result statemnet  seems at odds with what I've learned about them.

why not "si tu avais besoin d'aide, je serais ravie de t'aider" as a second condtional   or

"si tu as besoin d'aide, je serai ravie de t'aider" as a first condtional?

If you don't know the person, how can you use te; si vous ne connaissez pas cette personne, comment peut-on utiliser te?

In the following example, I am struggling to understand why we must use la and not lui? To me, it sounds like the sentence requires an indirect object pronoun, because the question "What" is not answered in response to the "must", which is the verb in this sentence. I use the "what" test to determine if there is a direct object in the sentence. With this sentence, should I consider "what must they warn" as my question, or "what must they do". Apologies if my line of thought is completely skewed but it seems to work in most cases. 

Does Julie know? We must warn her ,
