I was just wondering if anyone had any ideas to help me learn whether a word starts with le or la.
There are no fast rules, you really just have to memorize. However, some words are more likely to be one than the other (for instance, words that end in consonants are more likely to be masculine, but this isn't the case for all nouns).
le is for masculine nouns and la is for feminine nouns
it depends on the word.
