(Removed prod.) This article conflates mathematical and linguistic uses of the symbol, implying that these uses are related. Two problems: First, the concepts in the two fields are quite different. The linguistic use is to represent a linguistic element that might be in that place but is not. The mathematical use is for a set that contains nothing; in particular, the set containing the empty set is different from the empty set, whereas no such distinction is evident in the linguistic use. Second, the term "null sign", in my experience, is not used for this symbol in mathematics.{{br}}It is possible (I wouldn't know) that this is in fact the standard name for this symbol in linguistics. In that case, an alternative to deletion would be to rewrite the article so as to make it entirely about linguistics, and remove the implication that the name "null sign" is used for the empty-set symbol in mathematics.
