long, passionate, vehement speech
The politician's speech was an hour-long harangue in which he basically denounced everyone and everything.
de (away)#terrere (frighten)
sounds like HARAYENGE (we will beat them). Imagine that our leaders are giving earnest speech on how we are going to beat terrorism. HAR (her) + ANGUE (anger) = she VERBALLY ATTACKED me because of HER ANGER at me. HARANGUE can be split as har + ang + u + e. so when YOU are ANGry with HAR (her), she is subjected to a long or intensive verbal attack. split it to HAR + LANGUE. HAR = harrass and LANG = language. hence harangue is harassing language
