The key word in most sentences, the word that reveals what is happening, is the verb.
It can declare something (You ran
), ask a question (Did you run?
), convey a command (Run faster!
), or express a wish (May this good weather last!
) or a possibility (If you had run well, you might have won; if you run better tomorrow, you may win
). You cannot have a complete English sentence without at least one verb.
Understandably, this multitalented part of speech can be analyzed and categorized in any of several ways. For example, this dictionary distinguishes between a transitive verb
, labeled “(used with object),” as in The country
fought two wars at the same time,
and an intransitive verb
, labeled “(used without object),” as in He
fought in both of them.
As we can see with fight,
some verbs can be either transitive or intransitive.
Another analysis is offered by the grammarians Quirk, Greenbaum, Leech, and Svartvik in their renowned A Comprehensive Grammar of the English Language.
They divide verbs into three categories: (1) modal auxiliary verbs, a short list comprising can, may, will, shall, could, might, would, should,
all of which are “helping” verbs, as in Congress
will vote tomorrow,
and (2) primary verbs, the smallest group—be, do,
—all three of which can be either auxiliaries (I
am leaving for school now; I
did finish my homework; I
have studied enough
) or main verbs (I
am happy; I
did my best; I
have a good teacher
), and (3) full verbs, the largest group by far, containing all the rest.
A third approach differentiates an action verb
from one that is stative
. An action verb expresses something you can do (run, study, sit, want
) or something that can happen (leak, end, appear, collapse
). In contrast, a stative verb expresses an ongoing state or condition (I know all the answers; we own our house; they fear failure
). Some verbs, like be,
are in both camps: In she is careless,
the verb is
is stative, describing a permanent trait. In she was being careless in losing those documents,
the verb was
is an action verb, describing a specific act of carelessness. The same mutability is seen in verbs of the senses (smell, taste, feel
): Mmm, smell that coffee
[action]; the coffee smells wonderful
We can also distinguish the linking verb
(more formally known as a copula
) from verbs that can take an object or be modified by an adverb. Linking verbs identify or describe a subject by connecting it with a noun, an adjective, or a prepositional phrase in a following complement
(she is a doctor; they were delighted; we will be at the party
). Other linking verbs, like feel, appear, smell, taste, look, become,
perform the same concatenating function. A number of them happen to be stative, but not all; get
for example, are both linking and action verbs (the weather got warmer yesterday; she acted surprised
). As we can see, a single verb can be categorized in more than one way, depending on which type of analysis we subject it to.
And finally, we can look at English verbs in terms of a number of grammatical features that are expressed by changes in their form or changes in the way sentences are constructed. These features are tense2
(such as present and past), voice
(active or passive), person
(first, second, or third), number
(singular or plural), and mood2
(such as indicative and subjunctive)—each defined at its own dictionary.com
