It is much more common for a French word to change its form to match some grammatical feature. For example, many French nouns and adjectives have special feminine forms; verbs can have a much wider variety of forms than in English.
In general, the French dictionary recognises most of these forms if properly spelt. However, if you have trouble finding your word then, after checking that is is properly spelt, you could try checking if it has one of the following endings and if so, try the "basic" form of the word as indicated:
Word ending | Explanation | How to make basic form |
---|---|---|
-euse | Feminine noun/adjective ending | Replace -euse with -eur. |
-trice | Feminine noun/adjective ending | Replace -trice with -teur. |
-x | Plural noun/adjective ending | Remove the final -x. |
OK, it might sound a silly question, but a common problem is that people try to use the French-English dictionary to look up a word that isn't actually French. The following might help you in this case:
