IPA: /ˌɪn.səˈnɛr.ɪ.ti/
KK: /ɪnˈsænɪˌtɛri/
Very dirty or unclean, making it possible for diseases to spread.
The insanitary conditions in the old building made everyone worried about their health.
Insanitary is formed from "in-" (meaning not) and "sanitas" (from Latin, meaning health). The word describes a condition that is not healthy or clean, hence referring to something that is unhealthy or unclean.
Think of 'not' ('in-') being combined with 'health' ('sanitas') to remember that 'insanitary' means something that is not healthy or clean.
