==== Questions ====

Both [[yes–no question]]s and [[wh-question|''wh''-questions]] in English are mostly formed using [[subject–auxiliary inversion]] (''Am I going tomorrow?'', ''Where can we eat?''), which may require [[do-support|''do''-support]] (''Do you like her?'', ''Where did he go?''). In most cases, [[interrogative word]]s (''wh''-words; e.g. ''what'', ''who'', ''where'', ''when'', ''why'', ''how'') appear in a [[Wh-movement|fronted position]]. For example, in the question ''What did you see?'', the word ''what'' appears as the first constituent despite being the [[grammatical object]] of the sentence. (When the ''wh''-word is the subject or forms part of the subject, no inversion occurs: ''Who saw the cat?''.) [[Prepositional phrases]] can also be fronted when they are the question's theme, e.g. ''To whose house did you go last night?''. The personal interrogative pronoun ''[[who (pronoun)|who]]'' is the only interrogative pronoun to still show inflection for case, with the variant ''whom'' serving as the objective case form, although this form may be going out of use in many contexts.{{sfn|Huddleston|Pullum|2002|pp=7–8}}
