Editing Interrogative word (section)

===Forms with ''-ever''===
Most English interrogative words can take the [[suffix]] ''-ever'', to form words such as ''whatever'' and ''wherever''. (Older forms of the suffix are ''-so'' and ''-soever'', as in ''whoso'' and ''whomsoever''.) These words have the following main meanings:
*As more emphatic interrogative words, often expressing disbelief or puzzlement in mainly [[rhetorical question]]s: ''Whoever could have done such a thing? Wherever has he gone?''
*To form [[free relative clause]]s, as in ''I'll do whatever you do'', ''Whoever challenges us shall be punished'', ''Go to wherever they go''. In this use, the nominal ''-ever'' words (''who(m)ever'', ''whatever'', ''whichever'') can be regarded as [[indefinite pronoun]]s or as [[English relative clauses|relative pronouns]].  
*To form [[adverbial clause]]s with the meaning "no matter where/who/etc.": ''Wherever they hide, I will find them.''

Some of these words have also developed independent meanings, such as ''however'' as an [[adverb]] meaning "nonetheless"; ''whatsoever'' as an emphatic adverb used with ''no'', ''none'', ''any'', ''nothing'', etc. (''I did nothing wrong whatsoever''); and ''[[whatever (slang)|whatever]]'' in its slang usage.
