Final answer:
Unsanitary and unsanitary do not share the same meaning. The prefix 'un-' reverses the meaning of 'sanitary,' resulting in the opposite meaning. Therefore, 'unsanitary' means not clean or hygienic, while 'sanitary' means clean and free from germs or dirt.
Step-by-step explanation:
False. Unsanitary and unsanitary do not share the same meaning. The prefix 'un-' means 'not' in English, so when added to the word 'sanitary,' it negates the meaning, resulting in 'not sanitary' or 'not clean.' Therefore, 'unsanitary' means not clean or not hygienic. On the other hand, 'sanitary' means clean, hygienic, or free from germs or dirt. So, 'sanitary' and 'unsanitary' have opposite meanings.
