ABSTRACT
He suggested that the second word might have been formed when the first acquired a prefix and then lost the glottal stop. (There are many other cases in Khmer, of course, where the glottal stop has been retained when prefixation has taken place, e.g. op /?aop/ 'to hold by putting the arms round'> ph-op /ph^aop/ 'to brace tightly together'.) This suggestion, which may account for some instances, would not, however, cover all cases since we could not assume that all bases originally had initial glottal stop.
