Ladygram (04/07/14) Clue 17: "Representing one half around bighead (2,6)". Pretty certain two letter word is 'on' and quite sure it starts with an 'o'. However, second 6 letter word has me stumped.
Also Clue 19: "Swell until very loud (4) - starts with a 'T'.
ANY help will be gratefully received.
Many thanks
