'Nouns are the types of words which give the names of things, people, places, happenings and ideas … Nouns can be singular (referring to one thing) or plural (referring to many). (Language into Languages Teaching, University of Glasgow, Scottish Executive Education Department, 2001)
All nouns in French are either masculine or feminine. In some other languages, including English, nouns can also be neuter.
In English the situation has more or less resolved itself into the use of the masculine for male humans or animals, feminine for female humans or animals, and neuter for objects or things. But things are not quite as simple as they seem. For example, in English we readily say:
'Look at that child. It’s going to run across the road.'
'The ship is on time. She will arrive at noon.'
In French, nouns which refer to objects or things are either masculine or feminine.
Nouns which refer to male humans or animals are, as in English, masculine; nouns which refer to female humans or animals are feminine.
The general rule is to add an 's', as in English. There are, however, exceptions. Some words which have irregular plurals are:
| animal | animaux |
| armoire de pharmacie | armoires de pharmacie |
| armoire de toilette | armoires de toilette |
| bureau | bureaux |
| cheval | chevaux |
| gâteau | gâteaux |
| genou | genoux |
| grand-mère | grands-mères (recommended thus by the Académie) |
| grand-père | grands-pères |
| hôpital | hôpitaux |
| lave-vaisselle | lave-vaisselle (invariable) |
| Madame | Mesdames |
| Mademoiselle | Mesdemoiselles |
| Monsieur | Messieurs |
| nez | nez (invariable) |
| nom de famille | noms de famille |
| rendezvous | rendezvous (invariable) |
| rez de chaussée | rez de chaussée (invariable) |

It can be observed that there are certain rules, but it is not necessary to develop the rules fully at this stage.
Some, simply stated, are:
