Spell check

For what common word could this be an alternative spelling:

Ghoughbteighpteau? That's p as in hiccough, o as in though, t as in debt, a as in neighbour, t as in ptomaine, o as in bureau.

Highlight the empty space for the answer, but not before you've had a go.
Clue: think of Shaw's method of spelling the word fish as GHOTI.
