As you seem to be having a bit of difficulty, I suppose I could go against my better judgment and give you a very big spoiler....

nwosti

Lol nice try but that isn't a word, so no

Lmao that made me laugh like hell haha nice one buddy hahahahahahahaha

is it chilly as in cold when u say its chillie out side
but when u eat chilly its pretty hot

Well done, right thinking but wrong answer (seeing as chilly and chilli are spelt differently )

Having thought about this myself for a few days, I reckon that there are four possible correct answers of which I would accept any one.

A contronym? I can't think of any 6 letter ones, well can only think of two tbh but neither 6 letters.

Yep, there are 4 I can think of (though one is also a heteronym so is more usually hyphenated to avoid confusion).

Cleave! I am right with that ain't i?

You most certainly are!

(And that was the word I was first thinking of - so bonus point for that lol)

These others are going to bug me for a while then!

What does the bonus point actually get me? Is it worth anything at all?

Perpetual admiration

Got more chance of winning the euromillions jackpot than getting all them points!

Lol
btw, if you are going to try for the others, I'd start with the heteronym one since the hyphenation comment I made is a HUGE clue as it gives a third of it away .

loool

i might be stupid (welsh)
i dont get how cleave is the answer can u explain to me the meanings please bud or damien

I have no idea what that one could be lol, but custom is another one!

Take 20 bonus point mate, I hadn't though of that one myself (so there are still 3 left lol)

Phased - Cleave can be to split apart or to stick together as in:

Cleave with an axe and Cleave together

Jeez how many is there?!?! I'm tempted to google but that'll ruin the satisfaction of getting these!

I know what you mean, I was made up that there was one I hadn't thought of and now I'm keen to rack my brains to see if I can come up with another one

Well I can't think of anymore! I will keep trying!
