根據英語文法,有很多情況, 冠詞是必須省略的,尤其是在專有名詞(proper noun)前, 例如: 人名、稱號、地方名、國家(除美國、菲律賓等例外)、城市 等等.
在感歎詞"O"後面的名詞一般是專有名詞,如 O Lord; O God; O Zeus; O Canada! 而 King of Beasts 是稱號, 用了大楷, 屬於專有名詞, 所以前面不用冠詞唷!
In many phrases the definite article may be omitted
The definite article is not needed in the predicate after the verb "be" It is used without a "the" after be=is.Definite article means "the". .An indefinite article a and an can be added. No "the" before a proper noun "King of Beast":-
eg:-It is King of Beast
=The King of Beast is O Lion!.
