I would like "When a man is tired of London he is tired of life"
translating into Latin

"I suggested a doubt, that if I were to reside in London, the
exquisite zest with which I relished it in occasional visits might go
off, and I might grow tired of it. Johnson: "Why, Sir, you find no
man, at all intellectual, who is willing to leave London. No, Sir,
when a man is tired of London, he is tired of life; for there is in
London all that life can afford."
Boswell, James, The Life of Samuel Johnson, L.L.D., September 20,
1777, page 733, Modern Library Edition, New York.

Latin supplies an idiomatic construction that conveys the sentiment
expressed by Johnson almost exactly, and it would have been familiar
to him, himself a competent Latinist. The impersonal verb taedet
combined with the accusative case of the person and the genitive case
of the thing produces a phrase that parallels the English.

For example, a man, homo, hominis, who is tired of life, vita, vitae,
would be hominem taedet vitae.

"When" is translated as the adverb "quando." The masculine personal
pronoun "he" is translated by the inflected form of "is", eum.

quando -- when

Taken altogether:

"Quando hominem taedet Londinii, eum taedet vitae."

A very thorough answer

Samuel Johnson may turn over in his grave just at the suggestion of
translating his words into Latin.  ;-)

The standard idiomatic phrase that expresses the sense of Dr.
Johnson's quip is formed around the impersonal verb taedet, with the
person in the accusative and the object in the genitive. Thus,
simplified, homines (man)  is declined to hominem and vita (life) to
vitae, and these are combined with the verb to construct the phrase
"hominem taedet vitae" -- "the man is tired or life." (Or "bored with"
or disgusted by," depending on the context.) The full sentence would
run, "Quando hominem taedet Londinii, eum taedet vitae" -- "When a man
is tired of London, he is tired of life."

Thank you for the rating.
