Any of the tags listed above may in theory be modified by the addition of a pair of numbers to it: eg. DD21, DD22 This signifies that the tag occurs as part of a sequence of similar tags, representing a sequence of words which for grammatical purposes are treated as a single unit. For example the expression in terms of is treated as a single preposition, receiving the tags:

		 in_II31 terms_II32 of_II33 
The first of the two digits indicates the number of words/tags in the sequence, and the second digit the position of each word within that sequence.

Such ditto tags are not included in the lexicon, but are assigned automatically by a program called IDIOMTAG which looks for a range of multi-word sequences included in the idiomlist. The following sample entries from the idiomlist show that syntactic ambiguity is taken into account, and also that, depending on the context, ditto tags may or may not be required for a particular word sequence:

		at_RR21 length_RR22
		a_DD21/RR21 lot_DD22/RR22
		in_CS21/II that_CS22/DD1
