Ridiculous question about charades?

[ClubMan]

I would think of there being a slur (musical one that is - not a drunken one ) joining the second and third syllable.

I can sort of see the argument for 3, but like others, I'd be pretty certain it's 4.

For 3 syllables you would be saying: "ca-sual-ty"

If you say it like this you are pronounsing the word wrong afaik. (Something to do with two different vowels side-by-side cannot make only one syllable (with acceptions)) So it is definitely 4!
