So many pet peeves from this crusty contributor.

A few of 'em:
whilst/amongst;
'new initiative' and 'period of time' (I know ... there are squillions of these, but these two really get on my wick);
the mispronunciation of 'exquisite' with the stress on the first 'i';
'honing in' on something;
'with regards to';
'fewer' where it should be 'less';
'thank-you' when it's not used as an adjective;
'infact', 'instore', 'alot' etc;
'lead instead of 'led'; and
'outside of'.

Hrmph! That's enough for the nonce.
