What are your views on focussed vs focused and focussing vs focusing....

[popsycal]

...before I go and make a fool of myself to DS1's teacher

Ta

My Chambers says both are possible.

My personal view is that the double s is an abomination.
Find another dictionary.

I know both can be used but is there a more acceptable version.... ialways use one over the other....

One S.

so iam right then.....

in ds1's spelling list he has focusing and
focussed

Don't know where the double "s" came from, I thought it was wrong till I consulted Chambers.

Surely you should decide one way or the other? Focus - focused - focusing (which would make sense because focus only has one s to start with) or focus - focussed - focussing (which I dislike).

That double s is a real bugbear of mine - I know it's allowed but I really don't like it.

Likewise tranquility/tranquillity. Bleurgh to the double l.

Should always be a single "s" in my opinion. I didn't even know a double "s" was permissible, it just doesn't look right.

Single S.

Double 's' is a US-style spelling, but is acceptable over here.

Should definitely stick to one or the other - focusing/focussed makes no sense.

Double 'S' doesn't look right - Americanism?

But my computer keeps coming up with 'Action Canceled' and that doesn't look right either! (Quite apart from the fact that it doesn't seem to mean anything.)
