00:00So, what is an infinitive?
00:02Infinitive is a non-finite verb.
00:05It is not the main verb in the sentence.
00:07It doesn't change as per the tense of the sentence, singular or plural subject or the type of person in
00:14the sentence.
00:15How it is created?
00:17It is created by adding to to the base form of the verb.
00:21Let's understand how to create infinitives with some examples.
00:25To convert verb run, which is in verb's base form, we add to before the word run.
00:33So, it becomes to run.
00:36To convert verb play, which is in verb's base form, we add to before the word play.
00:43So, it becomes to play.
00:44To convert verb eat, which is in verb's base form, we add to before the word eat.
00:52So, it becomes to eat.
00:53Now, we have understood how we can create an infinitive.
00:57Let's understand the use of infinitive.
01:00From earlier discussion, we know infinitives are not used as a main verb in the sentence.
01:06They are instead used as a noun, adjective, or adverb in the sentence.
01:13Let's understand how infinitives are used as a noun.
01:17Sia likes to play.
01:19Here, to play is used as an object in the sentence.
01:23So, it behaves as a noun.
01:25Let's see next example.
01:27I want to write.
01:28Here, to write is used as an object in the sentence.
01:32So, it behaves as a noun.
01:34Let's see one more example.
01:37To dance is her hobby.
01:39Here, to dance is used as a subject in the sentence.
01:44So, it behaves as a noun.
01:46So, we have understood how infinitives are used as a noun.
01:50Let's understand how infinitives are used as an adjective.
01:53I have no time to eat.
01:56Here, no time is an object.
01:58And to eat is used to discredit that object.
02:02So, to eat is an adjective here.
02:05Let's see next example.
02:07That was a game to watch.
02:09Here, in this sentence, to watch tells us something more about the quality of the game, which is a noun.
02:16Describing the noun is a verb of an adjective.
02:19So, to watch is an adjective here.
02:22I told you to wait.
02:24Here, to wait is used to describe what was expected from the subject.
02:29So, to wait is used as an adjective here.
02:31Here, we have understood how infinitives are used as an adjective.
02:37Let's understand how infinitives are used as an adverb.
02:42She reads to gain knowledge.
02:44Here, to gain is describing the verb read.
02:48So, to gain is used as an adverb here.
02:52Let's see next example.
02:54Her voice is pleasant to hear.
02:57Here, who hear is describing the adjective pleasant.
03:00So, to hear is used as an adverb here.
03:05Let's see one more example.
03:07The new soldiers were ready to listen and obey.
03:10Here, to listen is describing the adjective ready.
03:14So, to listen is an adverb here.
03:18So, here we have understood how infinitives are used as an adverb in the sentence.
03:23Let's look into an exceptional case related to infinitives.
03:27We understood that infinitives are cleared by adding two to verb's base form.
03:34But, there are some cases where it is not added to the verb and then also it acts as an
03:41infinitive.
03:42These infinitives are called bare infinitives.
03:46So, when an infinitive is used without the marker 2, it is called a bare infinitive.
03:53Let's see sentence example of bare infinitives.
03:56She made me cry.
03:59Here, cry is a bare infinitive as we haven't written to cry.
04:03Let's see one more example of bare infinitive.
04:05Here, I heard him sing a lovely song.
04:08Here, sing is a bare infinitive as we haven't written to sing.
04:13So, bare infinitive acts as infinitive only but without a to attached to the verb.
04:19That's all about infinitives in this video.
04:22Let's quickly revise what we have learned in this lesson.
04:24Firstly, we understood that infinitives are not the main verb in this sentence.
04:29They are created by adding to before the verb's base form.
04:34Then, we understood that infinitives are not used as a verb in the sentence.
04:39Instead, they are used as noun, adjective or actual in the sentence.
04:44And finally, we understood the term bare infinitives.
04:48They are infinitives without a to added before a verb.
04:52So, that's all in this video.
