Blatant

Blatant is one of those rare words which have a clear and definite origin:

It was coined by the English poet Edmund Spenser (c. 1552-1599) in his 1590s epic poem  The Faerie Queen 

It is an allegorical work of fantasy which mythologises England (using native myths, such as St George) as a great Christian nation, ruled over by ‘Gloriana’ (i.e. Queen Elizabeth I). 

The meaning of the word ‘blatant’ is, one suspects, blatantly obvious. But how it arrived at its modern meaning is not.

The word has a curious history within the world of English poetry, and ‘blatant’ took its time to arrive at its modern definition.

The origin of its meaning is perhaps one of the most curious in all of the English language.
