We have two words today, because they are both from the same book, and I did not wish to choose between them.
 

Salubrious / Obliquity

 
Salubrious, adjective: favourable to or promoting health or well-being.

-salubriously, adverb.

-salubriousness, noun.

-salubrity, noun.

[Origin: Latin salubris; akin to salvus safe, healthy.]

(1547)

“Bloomsbury to the north and Soho to the west were far from salubrious parts of London, but St. Giles’s remained one of the worst blackspots on the London map until the 1890s.” – Rivals of the Ripper: Unsolved Murders of Women in Late Victorian London, Jan Bondeson.

Obliquity, noun, plural -ties.

1: deviation from moral rectitude or sound thinking.

2a: deviation from parallelism or perpendicularity; also: the amount of such a deviation. b: the angle between the planes of the earth’s equator and orbit having a value of about 23°27′.

3a: indirectness or deliberate obscurity of speech or conduct. b: an obscure or confusing statement.

[Origin: Middle French obliquité from Latin obliquitatem slanting direction, obliquity.]

(15th Century)

“The Era newspaper blamed the police for their hounding of Smith and insisted that ‘the mental obliquity and professional incapacity displayed by the police in getting up the case against Smith, for the Cannon Street murder, shows more than ever the absolute necessity that exists for the establishment of a public prosecutor’. – Rivals of the Ripper: Unsolved Murders of Women in Late Victorian London, Jan Bondeson.

These two words definitely do not belong together, but I love the way they sound together: Salubrious Obliquity.
