Translation guide
The English word 'cum' has two main uses: a preposition meaning 'combined with' or 'also used as', and a slang noun for semen or orgasm. This guide covers both, with a focus on natural Japanese equivalents.
Expressing that something serves two functions or roles simultaneously, often in a hyphenated compound like 'kitchen-cum-dining room'.
The most common way to express 'cum' in the sense of 'also serving as'. Attach 兼 (けん) between two nouns to indicate dual purpose.
この部屋は書斎兼客間です。
This room is a study-cum-guest room.
彼は運転手兼ガイドとして働いている。
He works as a driver-cum-guide.
Referring to semen or the act of ejaculation/orgasm in a vulgar or informal context.
Do not use カム or クム to translate the preposition 'cum'. These are not understood in Japanese. Use 兼 or related patterns instead.
ザーメン and イク are casual and often vulgar, suitable for informal or sexual contexts. 精液 and 射精する are clinical and appropriate for medical or formal discussions. Choose based on context.
A more descriptive pattern using the verb 兼ねる (to serve both as). Often used when the dual function is more nuanced or when modifying a noun.
応接室を兼ねたオフィス
an office-cum-reception room
Used for objects designed for dual use. 兼用 (けんよう) means 'combined use'.
兼用のキッチン
a kitchen-cum-dining room
The most common slang term for semen, borrowed from German 'Samen'. Used in casual and vulgar contexts.
彼はザーメンを飲み込んだ。
He swallowed cum.
The formal/medical term for semen. Not slang, but can be used in explicit contexts.
精液の検査をした。
