for the Weekly Prompts Weekend Challenge of 27 March 2021, frightful. I beg pardon to any UK readers – I realise this is a UK prompt but most of my readers are probably more familiar with American pronounciations.
As a fog-horn, was not out of place,
For his singing, might wish to erase,
While he started, delightful,
He then tailed off to frightful,
As he shattered his cut-crystal vase.
