Word of the day: sesquicentennial

The word refers to a period of 150 years or the 150th anniversary of an event. We are about to commemorate in a week’s time the 150th anniversary of a major historic event, so you will see the word used and reports on the anniversary – remember where you saw it first.

The event I am thinking of occurred on 12 April 1861. It was the Battle of Fort Sumter which started the bloody, four-year American Civil War.
