Question:

What is a good rule of thumb for knowing what gender a noun is in French?

Inactive
Emma H.
Answer:

Sadly, there is no one rule that will help you know the gender of any given noun in French. However, there are some tricks that can help speed up the process. For instance, nouns that end in -urde; -ade; -ude; -euse; -anse; -ense; -ière; -tion; -sion; will usually be feminine. On the other hand, words that end in -er; -oir; -isme; -ard; -int; -ant; -ent; -ond; -ont; -and; will usually be masculine. In **most** cases, words that end with consonants will be masculine. Of course there are exceptions, and subtleties can only be acquired with a LOT of practice.

Answer:

An enzyme is a catalyst because is speeds up the speed of a chemical reaction AND it remains intact by the end of the reaction, meaning that it acts at very low concentrations. It transforms a substrate into different products.
