English verbs

language culture Maturity 11-13 Next article →

Verbs are a fundamental part of speech in the English language. They function as the engine of a sentence by expressing actions, occurrences, or states of being. While English verbs are not heavily inflected, meaning they do not change their endings very often, they are essential for providing meaning. Most combinations of tense, aspect, mood, and voice are expressed periphrastically. This means English uses auxiliary verbs, also known as helping verbs, to create complex meanings. Without verbs, it would be nearly impossible to communicate the timing or nature of events.

To understand how verbs function, one must look at their principal parts. A regular verb has only one principal part, known as the base form or dictionary form. For example, the base form "exist" can predictably produce "exists," "existed," and "existing." In contrast, irregular verbs typically have three principal parts. These are often labeled as V1 (the base form), V2 (the past simple), and V3 (the past participle). For instance, the verb "write" uses "write" as its base, "wrote" as its past tense, and "written" as its past participle. While some textbooks use these V1, V2, and V3 labels, the convention has largely faded from modern British and American usage.

Verbs change their shape through a process called inflection. The most common inflection is the third person singular present tense, which usually adds an "-s" suffix. For a simple verb like "run," this results in "runs." However, specific spelling rules apply depending on the word's ending. If a verb ends in a sibilant sound, such as "buzz," you must add "-es" to create "buzzes." If a verb ends in a consonant plus "y," such as "cry," the "y" changes to an "i" before adding "-es," resulting in "cries." These rules for verbs are very similar to the rules used for making nouns plural.

Another major inflection is the past tense, or preterite. For regular verbs, this is typically achieved by adding "-ed" to the base form, such as turning "play" into "played." There are complex rules regarding consonant doubling in this stage. If a base form ends in a single vowel followed by a single consonant, the consonant is often doubled, like "ship" becoming "shipped." This doubling helps keep the vowel sound short. In British English, the letter "l" is often doubled regardless of stress, such as in "travelled." The pronunciation of this ending also varies based on the preceding consonant sounds.

Beyond regular patterns, English contains about 200 irregular verbs. These verbs do not follow the standard "-ed" rule for their past tense or past participle forms. Some irregular verbs, like "send," use the same form for both the past tense and the past participle: "sent." Others, like "sing," have entirely different forms for each stage: "sing," "sang," and "sung." The most irregular verb in the entire language is the copular verb "be." It possesses a wide variety of forms, including "am," "is," "are," "was," "were," "been," and "being."

The history of English verbs is a story of many different influences. Many of the most common verbs and nearly all irregular verbs originated from Old English. However, English has also borrowed heavily from other languages. Many verbs were taken from Latin or French. Some words were created through conversion, where a noun or adjective becomes a verb. For example, the adjectives "separate" and "direct" became verbs starting in the 16th century. Other verbs were formed by adding suffixes like "-ate" to Latin roots, such as "capacitate," or by adapting French words like "isolate."

Verbs also include specialized categories like modal and defective verbs. Modal verbs, such as "can" and "must," are considered defective because they are used in only a limited number of forms. They do not follow the same inflectional patterns as standard verbs. Understanding these different classes is vital for mastering English syntax. By combining base forms, auxiliary verbs, and various inflections, speakers can navigate complex ideas. This system allows for precise communication across different times, moods, and social contexts.
