Woke was officially added into the Oxford English Dictionary as an adjective in June 2017.
The dictionary defines it as “originally: well-informed, up-to-date. Now chiefly: alert to racial or social discrimination and injustice”.
The Urban Dictionary, which published its original definition two years prior to the official dictionary, defines it as “being woke means being aware… knowing what’s going on in the community (related to racism and social injustice)”.
In other words, it means to be awake to sensitive social issues, such as racism.https://inews.co.uk/news/uk/woke-what-mean-meaning-origins-term-definition-culture-387962
