請問英文的綽號需要大寫嗎? 比如nini需要寫成Nini嗎?

依文法規定，只要是專有名詞頭一字母均必須大寫，Nini是給某人專有的綽號，是專屬的，故必須大寫。

Common first female names Naomi, Nina and Frederic, Nini as the nick names in various spellings has been common among friends as an informal,humorous name for a person connected with their real name,personality,appearance of what they have done;eg:-She was nicknamed "Nini".

要大寫喔！

要喔!綽號也等同於比較不正式的名字啊!名字要大寫，綽號當然也要大寫。比較嚴格的說法是"稱呼別人"都要大寫!
