prophylactic
proh-fuh-LAK-tik
/ˌproʊ.fɪˈlæk.tɪk/
Intended to prevent disease or health problems before they occur.
Focuses on active protection put in place prior to disease onset rather than treating active illness.
The story behind the word. From Greek 'prophylaktikos', combining 'pro-' (before) and 'phylax' (a guard or keeper). It literally means placing a guard ahead of time to block sickness before it enters.
Word relationships
