The organizers have done me the honour of inviting me to give the keynote address, which I have decided to call Dear Professor Wells. I will discuss some of the emails I have received over the past few months (mainly concerning LPD) and how I have answered them. This gives an insight into the points in English phonetics that I have evidently not explained clearly enough in the dictionary or elsewhere.
Some of the questions people ask are extremely sophisticated. Others are anything but. Fortunately not all emails I receive are as laconic and unanswerable as one that reached me recently from an address in Saudi Arabia:
hi.. i'm from ksa
i want to teach english
Another, laconic but easily answered, read
Are you a man?—to which the answer is yes.
