Joint favourites CORNWALL and ISLAND.
In answer to Noondial – “my” as an exclamation (my, what a horrible mess you’ve made) has been known to be very craftily hidden as a possessive pronoun in that other cryptic and it often fools the most experienced solvers.
As for ALLEGE, I did once hear in court a lawyer on the other side say – I denounce the allegations and the “allegators” who made them. He also described my brief as something that was “strange credulity” (he obviously was trying to say it strained credulity). Both still make me giggle.
