A grown male horse that has not been castrated — one that can father foals. That last part is the whole point of the word.

A grown male horse是一匹成年的公馬，that has not been castrated沒有被閹割過，— one that can father foals——也就是能讓母馬懷孕生小馬的公馬。 That last part is the whole point of the word最後那一點正是這個字的重點。

A male horse that has been castrated is a gelding, and most riding horses are geldings, so 'stallion' is not simply the word for 'boy horse'. It is the word for one kept whole, usually for breeding, and often a valuable animal in a stud farm's records.

A male horse that has been castrated is a gelding被閹割過的公馬叫 gelding（閹馬），and most riding horses are geldings而大部分用來騎乘的馬都是閹馬，so 'stallion' is not simply the word for 'boy horse'所以「stallion」不是單純指「公的馬」而已。 It is the word for one kept whole這個字是指那種沒被閹割、保持完整的公馬，usually for breeding通常是留著配種用的，and often a valuable animal in a stud farm's records在種馬場的紀錄裡往往是很珍貴的動物。

Stallions have a reputation for being strong, spirited and hard to handle, and English leans on that. Call a man a stallion and you mean he is physically impressive and sexually attractive or active. It is informal, a bit crude, and usually said as a compliment or as a joke between friends — but it is about sex, so it is not something to say at work or to a stranger.

Stallions have a reputation for being strong, spirited and hard to handle種馬給人的印象是強壯、性子烈、不好駕馭，and English leans on that英文用這個字時就是靠著這個印象。 Call a man a stallion如果你叫一個男人 stallion，you mean he is physically impressive and sexually attractive or active意思是他身材很猛，性方面很有魅力或很活躍。 It is informal, a bit crude這是口語，有點粗俗，and usually said as a compliment or as a joke between friends通常是朋友之間拿來稱讚或開玩笑的話——but it is about sex但因為講的是性方面的事，so it is not something to say at work or to a stranger所以不適合在職場上或對陌生人說。
