外網回復：A lexicon is a list of words that belong to a particular language. A dictionary is a list of words and phrases that are (or were) in common usage, together with their definitions - so a dictionary is different from a lexicon because a lexicon is a simple list and doesn't define the words.
lexicon是屬於特定語言的單詞列表。 dictionary是壹個（或曾經）常用的單詞和短語及其定義的列表-因此，lexicon與dictionary不同，因為lexicon是壹個簡單的列表並且未定義單詞。
