Main Verb PhrasesTraditional grammar categorizes verbs by tense, then equates tense with real world timeIn reality, there are three grammatical concepts indicated in the main verb phraseTense, Modality, and Aspect
Main Verb PhrasesThese concepts overlap real-world time, but are not the same thing
Why three categories?
The three categories occur as distinct forms
In other words, they are marked in three different ways in the main verb phrase
Main Verb PhrasesThe Main Verb Phrase consists of the main verb, plus all the forms that show its tense, modality, and aspect
Tense
For our purposes, tense is a grammatical concept
Main Verb PhrasesTense determines the form of the verb
For historical reasons buried in the past, English is inflected for only two tenses: past and present
We show future, but in other ways
Main Verb PhrasesExamples:
“I walked my dog” (action in the past)
“I walk my dog every day” (indicates habitual action)
“Her plane leaves in three hours” (indicates future event)
Main Verb Phrases“Then I say . . . , then she says . . . , they I say” ( indicates past event)
Tense must occur in a verb phrase serving as a predicate
A verb that exhibits tense is said to be finite
Main Verb PhrasesA verb that does not exhibit tense is said to be non-finite
This is also called the base form
Main Verb PhrasesModality
We also classify sentences in English according to purpose
Indicative – makes statements
“Polynesians ruled Hawaii until 1788”
Main Verb PhrasesInterrogative – asks questions
“Why does cancer frustrate microbiologists?”
Imperative – gives commands
“Turn in your homework by noon on Friday”
Main Verb PhrasesConditional - indicates possibility
“Women athletes can compete against men in most sports”
Normally we make the conditional by adding certain words called modal auxiliaries
Page 195 of your book has the list – also on page 106
Main Verb PhrasesIf a modal auxiliaries occurs, it is always at the beginning of the main verb phrase
Since they concern possibility, they have come to be associated with expressing futurity
Main Verb PhrasesAspect
Indicates that the action of a verb is either completed or continuing
Aspect occurs in two forms:
Perfect
Progressive
Main Verb PhrasesPerfect
Indicates completed action
It is indicated by the auxiliary HAVE followed by a PAST PARTICIPLE
Please note that HAVE = have, has, had, having (page 106)
Main Verb PhrasesExamples:
“The astrologist had predicted an earthquake in May”
This is known as the PAST PERFECT
“Political relationships have unraveled on almost every continent”
Main Verb PhrasesThis is known as the PRESENT PERFECT
Note that both sentences refer to completed actions
Main Verb PhrasesTherefore, you must understand that the word “past” in PAST PARTICIPLE does not refer to real-world time, but only to the form of HAVE
Main Verb PhrasesTo construct the PAST PARTICIPLE
For regular verbs, add –ed
For some, add –n or –en
Driven
Some don’t change
Become - become
Main Verb PhrasesAnother way to think about it:
A PAST PARTICIPLE is the form of the verb that can follow HAVE
Main Verb PhrasesProgressive
Refers to continuing action
It is indicated by auxiliary BE followed by a PRESENT PARTICIPLE
BE = be, am, is, are, was, were, been, being (page 106)
Main Verb PhrasesExamples:“John Travolta was dancing in Brooklyn” This is known as the PAST PROGRESSIVE“Beth is crying”This is known as the PRESENT PROGRESSIVE
Main Verb PhrasesAgain the words “past” and “present” refer only to tense form, not real-world time
The PRESENT PARTICIPLE is always -ing (no exceptions to this rule)
Main Verb PhrasesPlease note – don’t be fooled by form
“Princess Diana was charming”
Here, “charming” is an adjective
vs.
“The Pope was charming his American audience”
Here, “charming” is a PRESENT PARTICIPLE
