The broader sense of "acronym" inclusive of terms pronounced as the individual letters (such as "TNT") is sometimes criticized, but it is the term's original meaning and is in common use. Language authorities such as dictionary and style guide editors are not in universal agreement on the naming for such abbreviations: in particular it is a matter of some dispute whether the term "acronym" can be legitimately applied to abbreviations which are not pronounced "as words"; nor do they agree on the correct use of space, case, and punctuation.
