Learn French: La confiture est très sucrée, mais la soupe est très salée. - The jam is very sweet, but the soup is very salty.

We use très (very) because it comes right before adjectives — in this case, sucrée (sweet) and salée (salty). You use beaucoup (a lot or much) to describe verbs (actions), like in J'aime beaucoup la soupe (I like soup a lot).

Why do sucrée and salée both end with an extra 'e'?

In French, adjectives change to match the gender of the noun they describe. Since la confiture (the jam) and la soupe (the soup) are both feminine nouns, we add a feminine e to the base masculine adjectives sucré and salé.

Does adding that extra 'e' change how sucrée and salée are pronounced?

No, they sound exactly like their masculine forms! The letter é (with the accent) makes an 'ay' sound, and the extra unaccented e added for the feminine form is completely silent.

If I wanted to say 'a lot of jam', would I use beaucoup or très?

You would use beaucoup de! While très means 'very' and is used with adjectives, beaucoup de means 'a lot of' and is used before nouns. So, 'a lot of jam' is beaucoup de confiture.
