In another thread(don't go there!) Rt Rev Musket said
"...It may be spoken "an honest" but according to the style guide I used to write papers under, you* write it "a honest."... "

I'm fascinated by the use of a honest.
Have you got a link?
Everything I've clicked so far seems to me to indicate an honest but that dialect can influence the choice. Yet you said you'd pronounce it an honest.

*btw if you reply I'd find it handy if you could use 'I' when referring to practices you follow( practices/ practises ? that might be the wrong spelling, sorry)

I should be in the garden. I'll check back tomorrow.
