This study takes a fresh approach to verb aspect in English - the nature of the action of a verb as to its beginning, duration, completion, or repetition with or without reference to its position in time. It provides an explanation as to why we choose one member of a different lexical pair as opposed to the other (e.g. do/make, look/see). Data used has been taken from a wide range of both spoken and written discourse and texts reflecting people's actual use of language presented in their relevant linguistic and situational contexts.
