N: 1. unsanitary, insanitary: Each of these words, based on a Latin word for “health,” means “unhealthy,” “likely to cause disease.” Although unsanitary is heard more often than insanitary, the latter is the preferred listing in five leading dictionaries. If conditions are so unclean, filthy, or contaminated as to be a threat to health, they may be called unsanitary or insanitary, as one chooses.
2. The adjectives insanitary and unsanitary both refer to dirty, unhealthy conditions or a lack of sanitary equipment. Unsanitary is the more frequent form in North America, while insanitary reflects British usage.
3. Cultural Interrelation: We can mention Oliver Twist (1837) by Charles Dickens (1812-1870) and the gritty realism with which Dickens portrays working class people and the horrible living conditions of the London slums.
