Key to the pronunciation

The pronunciation system used in revised material differs in some respects from that used in the Second Edition. In addition, the revised material includes not only British but also U.S. pronunciations.

For these reasons, two separate pronunciation keys are given here, one for Second Edition entries and one for entries in the New Edition.

• Go to the Key for Second Edition entries
• Go to the Key for New Edition entries

For further details, see the pronunciation section of the Preface to the Third Edition.
