Missing words meme

I found myself inadvertently contemplating the word 'inadvertent' the other day and trying to decide whether or not I ever did anything 'advertently'. This led me on to thinking about other words which seem to have part of a pair missing.

1. Impregnable - who or what is said to be pregnable? Keep it clean...
2. Impeccable - for example, my own dress sense could be seen as peccable.
3. Incognito - and then obviously you're cognito once you've been recognised?
4. Uncanny - although if you're a Geordie or a Scot you might still use canny in something approaching the sense of this.
5. Uncouth - Madam, I have never been couth, and resent the implication!
6. Antidote - Yeah, you know what an 'anti-venom' is. But an antidote? The nearest I can think of is that it might stop people doting on you...

Of course, they aren't always half a pair. Dishevelled comes from the Old French deschevelé and therefore you would not expect to find someone looking 'shevelled'. Inept is another, coming from the Latin ineptus meaning foolish.

However, your meme mission, should you choose to accept it, is a tripartite task. Firstly, think of two words not already mentioned here that fit into the category. Secondly, use them in conversation as regularly as possible over the next week. Thirdly, if you can, repost the details of this entry, together with your new words, and challenge others to do likewise.
