lis = conjugation of "to read" for "je" and "tu"
lit = conjugation of "to read" for "il", "elle", or "on" http://conjugator.reverso.net/conjugation-french-verb-lire.html
Also, as a side note, "lit" as a noun means "bed".
see, it is these kinds of things that duo lingo is missing and could really benefit from if they offer some reading on this kinda stuff when new words are introduced. I cannot properly translate if I do not know the rules of the language. any websites you'd recommend I look up to learn more about the rules and syntax?
http://www.youtube.com/user/imagiers?feature=g-user-u I like his lessons. In the first ones he explanes the differences in pronunciation and other things
The French language assigns genders to nouns - masculine or feminine. The word "menu" is a masculine noun. The indefinite article that goes with masculine nouns is "un" (a/an in English), the feminine is "une" (a/an in English). The definite articles are "le" for masculine (the), and "la" for feminine (the again). The plural versions are "les" (the) for definite and "des" for indefinite (this one is tricky and can mean different things in English, but in general for now let's say that the English equivalent is either "some" or no article at all).
There isn't really a trick to determine if a noun is masculine or feminine, you just have to learn the gender with the word. Incidentally, if you hover your mouse cursor of "menu" in the French sentence, they show the gender of the word along with definitions.
Hope that helps!
"Un" does mean "one," yes. But as an article, "un" (the masculine) and "une" (the feminine) both mean "a", because that is the singular article in English. We don't say "I am reading one menu;" the fact that we are only one person and therefore only need one menu is understood with the context! Hope this helps!
