You underlined the past participle of the lexixal verb JUMP. This, with the auxiliary verb HAVE. forms the present perfect of JUMP.I have jumped over a fence three times.
What is the verb in the previous sentence?Please don't make that sort of request, Brad. Any member who has the knowledge is free to respond to any question.Could a mature teacher who is currently teaching (not a moderator) please explain the difference between tense and aspect?
Modern grammarians tend to use the word tense for those forms of the verb which, by the presence or absence of inflection, locate a situation in time. For these grammarians, English has only two tenses, the uninflected/unmarked form, usually known as the present and the marked/inflected form usually known as the past. When not combined with any aspect, the tenses are usually known as the present simple and the past simple.
The word aspect is often used for verb forms that refer to some way of looking at the situation in time, such as its duration or completion. The two aspects generally recognised in English are the perfect, formed with the auxiliary HAVE and the third form (past participle) of the verb, and the progressive (or continuous), formed with the auxiliary BE and the -ing form of the verb. The auxiliaries show tenses; we thus have the present and past perfectand present and past progressive aspects. The aspects can combine, giving us the present and past perfect progressive aspects.
Some people refer to all the aspects as tenses. This is not really a problem for learners.
