As with ,any words from foreign languages which have their own alphabets, there is no universally accepted way of transcribing the Tamil name of this food into English. The
Concise Oxford Dictionary (1999) lists the word at poppadom, but mentions poppadum and popadom, as alternatives. The variant spellings which have been listed in Oxford dictionaries include papadam, pappadom, papadom, papadum, papodam, papodum, papadam, pappadam, poppadom, poppadum, poppodam, puppadum, puppodam, puppodum. However, there is nothing to say that you cannot use the unlisted spellings papodom, popadum, poppodom, poppodum, puppadam, puppadom and puppodom. Take your pick!
