The majority of French words derive from Vulgar Latin or were constructed from Latin or Greek roots. In many cases a single etymological root appears in French in a "popular" or native form, inherited from Vulgar Latin, and a learned form, borrowed later from Classical Latin. The following pairs consist of a native noun and a learned adjective:
However, a historical tendency to gallicise Latin roots can be identified, whereas English conversely leans towards a more direct incorporation of the Latin:
There are also noun-noun and adjective-adjective pairs:
It can be difficult to identify the Latin source of native French words, because in the evolution from Vulgar Latin, unstressed syllables were severely reduced and the remaining vowels and consonants underwent significant modifications.
More recently the linguistic policy of the French language academies of France and Quebec has been to provide French equivalents to (mainly English) imported words, either by using existing vocabulary, extending its meaning or deriving a new word according to French morphological rules. The result is often two (or more) co-existing terms for describing the same phenomenon.

It is estimated that 12% (4,200) of common French words found in a typical dictionary such as the Petit Larousse or Micro-Robert Plus (35,000 words) are of foreign origin (where Greek and Latin learned words are not seen as foreign). About 25% (1,054) of these foreign words come from English and are fairly recent borrowings. The others are some 707 words from Italian, 550 from ancient Germanic languages, 481 from other Gallo-Romance languages, 215 from Arabic, 164 from German, 160 from Celtic languages, 159 from Spanish, 153 from Dutch, 112 from Persian and Sanskrit, 101 from Native American languages, 89 from other Asian languages, 56 from other Afro-Asiatic languages, 55 from Slavic languages and Baltic languages, 10 from Basque and 144 (about 3%) from other languages.
One study analyzing the degree of differentiation of Romance languages in comparison to Latin estimated that among the languages analyzed French has the greatest distance from Latin. Lexical similarity is 89% with Italian, 80% with Sardinian, 78% with Rhaeto-Romance, and 75% with Romanian, Spanish and Portuguese.
The French counting system is partially vigesimal: twenty (vingt) is used as a base number in the names of numbers from 80 to 99. The French word for 80 is quatre-vingts, literally "four twenties", and the word for 75 is soixante-quinze, literally "sixty-fifteen". This reform arose after the French Revolution to unify the different counting systems (mostly vigesimal near the coast, because of Celtic (via Breton) and Viking influences). This system is comparable to the archaic English use of score, as in "fourscore and seven" (87), or "threescore and ten" (70).
In Old French (during the Middle Ages), all numbers from 30 to 99 could be said in either base 10 or base 20, e.g. vint et doze (twenty and twelve) for 32, dous vinz et diz (two twenties and ten) for 50, uitante for 80, or nonante for 90.
Belgian French, Swiss French, Aostan French and the French used in the Democratic Republic of the Congo, Rwanda and Burundi are different in this respect. In the French spoken in these places, 70 and 90 are septante and nonante. In Switzerland, depending on the local dialect, 80 can be quatre-vingts (Geneva, Neuchâtel, Jura) or huitante (Vaud, Valais, Fribourg). Octante had been used in Switzerland in the past, but is now considered archaic, while in the Aosta Valley 80 is huitante. In Belgium and in its former African colonies, however, quatre-vingts is universally used.
French, like most European languages, uses a space to separate thousands. The comma is used in French numbers as a decimal point, i.e. "2,5" instead of "2.5".
