Up to the mid/late 1980s, it was thought that some languages lacked a verb phrase. These included languages with extremely free word order (so-called non-configurational languages, such as Japanese, Hungarian, or Australian aboriginal languages), and languages with a default VSO order (several Celtic and Oceanic languages). The current view in some varieties of generative grammar (such as

reject the former. That is, among VPs, dependency grammars acknowledge only non-finite VP constituents:
(2) John
has finished the work. - Finite VP in bold
(3) John has
finished the work. - Non-finite VP in bold
Since
has finished the work contains the finite verb
has, it is a finite VP, and since
finished the work contains the non-finite verb
finished but lacks a finite verb, it is a non-finite VP. Starting with

Dependency grammars point to the results of many standard

to back up their stance. For instance,
topicalization,
pseudoclefting, and
answer fragments suggest that non-finite VP does but finite VP does not exist as a constituent:
(2) a. *...and
has finished the work, John. - Topicalization
- b. *What John has done is has finished the work. - Pseudoclefting
- c. What has John done? - *Has finished the work. - Answer fragment
The * indicates that the sentence is bad. These data must be compared to the results for non-finite VP:
(3) a. ...and
finished the work, John (certainly) has. - Topicalization
- b. What John has done is finished the work. - Pseudoclefting
- c. What has John done? - Finished the work. - Answer fragment
The strings in bold are the ones in focus. Attempts to in some sense isolate the finite VP fail in (2a-c), but the same attempts with the non-finite VP in (3a-c) succeed.
VPs narrowly defined
Verb phrases are sometimes defined more narrowly in scope to allow for only those sentence elements that are strictly considered verbal elements to form verb phrases. According to such a definition, verb phrases consist only of main verbs, auxiliary verbs, and other

constructions. For example, in the following sentences only the words in bold would be considered to form the verb phrase for each sentence:
(4) a. John
gave Mary a book.
- b. They were being eaten alive.
- c. She kept screaming like a maniac.
- d. Thou shall not kill.
This more narrow definition is often applied in functionalist frameworks and traditional European reference grammars. It is incompatible with the phrase structure understanding of the verb phrases, since the strings in bold are not constituents under standard analyses. It is, however, compatible with those grammars, in particular
