[Chalky] You are of course correct - and <hidden> The "beginning" was signifying the first letter of "your" i.e. the Y - The order of the parts was I hope implicit in the way the clue was phrased - once you get that "an afterthought" was PS then that would normally precede whatever the text of the PS was, if you see what I mean. <\hidden>
How about another (easy I think) .... a bit nudge, nudge this one ! Secreted when you hear loose woman is satisfied ? (7)
Now - could this one be something like HOARDED? ie. sounds like 'Whore did'? . I will attempt to find a couple of clues to post - I appear to be all 'take' and no 'give'.
