As the basic notion in cognitive grammar, construal is expounded from various aspects in terms of different conversational purposes in linguistic communication. Based on the well-discussed dimensions of construal from Langacker’s view, this study investigates the dimensions of construal from a dialogic view, particularly in cases of English wh-dialogues, with the aim of deciphering how the dialogic focus, the wh-word positioned at the head of the wh-question, is cognitively grounded in the answer. According to the ways that such wh-words are grounded, the dynamic adjustment of dialogic focuses in wh-dialogues is then examined, hopefully to shed some light on the interpretation of the utterance meaning from a dialogic view.
