English also has a present perfect continuous (or present perfect progressive) form, which combines present tense with both perfect aspect and continuous (progressive) aspect: "I have been eating". The action is not necessarily complete; and the same is true of certain uses of the basic present perfect when the verb expresses a state or a ...
The perfect can also be combined with another aspect [21] that is marked in English – the progressive (or continuous) aspect. In perfect progressive (or perfect continuous) constructions, the perfect auxiliary (a form of have) is followed by the past participle been (from be, the auxiliary of the progressive aspect), which in turn is followed ...
Apart from what are called the simple present (write, writes) and simple past (wrote), there are also continuous (progressive) forms (am/is/are/was/were writing), perfect forms (have/has/had written, and the perfect continuous have/has/had been writing), future forms (will write, will be writing, will have written, will have been writing), and ...

[4] If the main verb is in one of the non-past tenses, the subordinate verb is usually in the present or perfect subjunctive (primary sequence); if the main verb is in one of the past tenses, the subordinate verb is usually in the ...
The terms perfective and perfect should not be confused.
