Sorry folks, got sidetracked yesterday and back at work now.
It was a friend who posed the question knowing that I enjoy words, I'm not sure if he said plurals were allowed, maybe not, because it's meant to be a bit of a tough teaser, I don't think it will do any harm for us to just post what we've come up with.
I came up with just one that met the criteria but did think there would be at least a few more, maybe scientific or technical terms.
Anyway, the one that I got was: PROMPTLY
Anymore would be good to see, no time limit with this, I just put it on for a bit of late night fun, so fire away with whatever you've got.
I'll check back in tonight, see ya later
