SEMI-IDIOMATIC PHRASAL VERBS
In semi-idiomatic combinations the lexical verb, generally speaking, keeps its literal or metaphorical meaning, while the particle is used as an aspectual marker of various kinds. By this we refer here to the way a particle with a verb in English can express the completion, beginning-point, end-point or high intensity of an event. Continuation, a kind of non-completion, can also be expressed. These notions are explained and discussed under the concepts of perfectivity and imperfectivity, respectively.
Aspect is seen here as the pattern of distribution through time of an action or state, and relates to such questions as its completion, beginning-point, end-point or high intensity, all kinds of perfectivity. Non-completion, which is a type of imperfectivity, can alternatively be expressed.
The following connotations of particles have been suggested:
1 beginning of an activity: doze off, switch on, start out

3 the bringing of an activity to an end or getting to a certain limit: eat up, catch up, drink up, fill up, heat up, mix up, use up, sweep up; count out, hear out, knock out, sort out, throw out, wear out; break off, call off, cut off, sell off, switch off

In phrasal verbs the notion of completion or bringing to an end is most clear in those cases in which there is a contrast with a single verb, as in use vs use up, eat vs eat up, drink vs drink up, knock vs knock out and so on. Compare I’ve used this detergent (i.e. some of this detergent) with I’ve used up this detergent (= there is none left); He knocked the burglar down the stairs with He knocked him out (= left him unconscious).
