It is not unknown for Jews to make up new words. It is part of the psyche of a people as rich in vocabulary as in history. But there is one four-letter word that is wonderfully redolent of service to the Anglo-Jewish community. It will not be found in any dictionary. It is frequently misspelt. But at this time of year, in particular, it should be on the lips of every thinking British Jew.
Bar- and batmitzvah celebrations happen to coincide with the onset of adolescence for many youngsters. Inevitably they will be experiencing a series of dramatic psychological changes and social occasions during this time can feel like an emotional obstacle course.

London Walks, one of the capital's longest established walking tour companies, offers an "Old Jewish Quarter" tour of the East End. I have been on several of their enlightening guided walks - they have scores of them - but I wondered about this one.

Birth rates are sky high and intensive care baby units are running out of space for cribs. But while British hospitals might buckle under these conditions, Jerusalem's Shaare Zedek Medical Centre is thriving.

The last time a Chief Rabbi was appointed, Stanley Kalms was the kingmaker. Now, more than 20 years later, Lord Kalms of Edgware says he would not want the job again. Not that it is on offer, or that anyone is likely to fill the role he had in selecting the then Dr Jonathan Sacks for the position. Kalms now regards it as a worthless search for a pretty unimportant post.
Lying on his back, arms above his head, tumbled golden curls against his pillow, tiny Chanochi Pearl looks a gorgeous, healthy toddler.
