ambassador是大使, 一國在一個駐在國只能有唯一的大使, 所以在專指一個國家的大使時, 它是不可數名詞, 不可用冠詞a, 但用冠詞the是正確的.
emissary是特使, 一國可能同時派遣多名特使到另一國, 所以特使是可數名詞,
不過, ambassador在泛指一種職銜或身份時, 它也可以是普通名詞, 可以用冠詞a, 也可以加s. 一個國家可以任命許多大使到許多國家, 他們一起當然是複數.
an ambassador, ambassadors舉例:
An ambassador is a person from a particular country who is meant to represent his country, or to aninternational organization.
At the most simplistic level, an ambassador acts as a representative for her
or his home country. Ambassadors usually live in a country different from
their home one and work as a delegate for and representative of their
home country in votes and activities.

因為president在一所大學中是唯一的, 不需要加不定冠詞a.參考資料： Cavalier精心解答
