Auxiliary verb 

An auxiliary verb is a helping verb that supports the main verb in a sentence. It helps to show tense (time), mood, voice, or possibility. Auxiliary verbs do not usually carry the main meaning of the sentence; instead, they work with the main verb to give more information. Common auxiliary verbs include “be,” “have,” and “do,” as well as modal verbs like “can,” “may,” and “must.” For example, in the sentence “She is reading,” the word “is” is an auxiliary verb that helps the main verb “reading.”

Auxiliary verbs are very important because they help form different tenses. For example, “She has finished her work” uses “has” to show the present perfect tense. They are also used to form questions and negative sentences. For example, “Do you like tea?” and “She does not play” use auxiliary verbs to change the sentence form.

Auxiliary Verb (सहायक क्रिया) वह क्रिया होती है जो मुख्य क्रिया की सहायता करती है। यह वाक्य में समय (tense), भाव (mood), वाच्य (voice) या संभावना (possibility) को व्यक्त करने में मदद करती है। सहायक क्रिया अपने आप में पूरा अर्थ नहीं देती, बल्कि मुख्य क्रिया के साथ मिलकर वाक्य को स्पष्ट बनाती है। जैसे “is,” “have,” “do,” “can,” “may,” “must” आदि। उदाहरण के लिए “She is reading” में “is” सहायक क्रिया है।

सहायक क्रियाएँ अलग-अलग काल (tenses) बनाने में बहुत महत्वपूर्ण होती हैं। जैसे “She has finished her work” में “has” present perfect tense को दर्शाता है। इनका उपयोग प्रश्न और नकारात्मक वाक्य बनाने में भी होता है। जैसे “Do you like tea?” और “She does not play” में सहायक क्रिया का प्रयोग हुआ है।

1. She is playing now. (Present Continuous – action happening now)
2. They are studying at the moment. (Present Continuous – ongoing action)
3. I was sleeping when you called. (Past Continuous – action in the past)
4. He was watching TV yesterday evening. (Past Continuous – past time)
5. She has finished her work. (Present Perfect – action completed recently)
6. I have seen this movie before. (Present Perfect – past experience)
7. They had left before I arrived. (Past Perfect – earlier past action)
8. He had completed the task on time. (Past Perfect – completed in past)
9. I will go tomorrow. (Simple Future – future time)
10. She will be waiting for you. (Future Continuous – ongoing future action)

हिंदी में समझें:

1. She is playing now. (अभी काम हो रहा है)
2. They are studying at the moment. (इस समय पढ़ रहे हैं)
3. I was sleeping when you called. (भूतकाल में काम चल रहा था)
4. He was watching TV yesterday evening. (कल शाम देख रहा था)
5. She has finished her work. (काम अभी-अभी पूरा हुआ है)
6. I have seen this movie before. (पहले देख चुका हूँ)
7. They had left before I arrived. (पहले ही जा चुके थे)
8. He had completed the task on time. (समय पर पूरा कर लिया था)
9. I will go tomorrow. (भविष्य में जाऊँगा)
10. She will be waiting for you. (भविष्य में इंतज़ार कर रही होगी)

Finite Verb

A finite verb is a verb that changes its form according to the subject (who is doing the action) and the tense (time of the action), and it can make a sentence complete by itself. In simple words, a finite verb shows who is doing the action and when the action is happening. For example: “She writes a letter.” Here, “writes” is a finite verb because it agrees with the subject “she” (singular) and shows present time. If we change the subject or time, the verb also changes: “They write a letter” and “She wrote a letter.” In each case, the verb changes according to the subject or tense, so these are finite verbs.

हिंदी में, Finite Verb (रूप बदलने वाली क्रिया) वह क्रिया होती है जो कर्ता (subject) और समय (tense) के अनुसार अपना रूप बदलती है और अकेले ही एक पूरा वाक्य बना सकती है। सरल शब्दों में, यह बताती है कि कौन काम कर रहा है और कब कर रहा है। जैसे: “She writes a letter.” यहाँ “writes” कर्ता “she” के अनुसार बदल रहा है और वर्तमान समय दिखा रहा है। यदि हम कर्ता या समय बदलते हैं, तो क्रिया भी बदलती है: “They write a letter” और “She wrote a letter।” इसलिए ये सभी finite verbs हैं क्योंकि ये कर्ता और समय के अनुसार बदलते हैं।

Non-finite verbs

Non-finite verbs are verbs that do not change according to the subject or tense of a sentence. This means they do not show time (past, present, future) and they cannot be the main verb alone. They are usually used with another verb and often end in -to or -ing, or appear in their third form. There are three common types: infinitive (to + verb), gerund (verb + ing), and participle (V3 or V1+ing used as adjective). For example: “I like to read books.” (infinitive), “Reading is fun.” (gerund), and “The broken window needs repair.” (participle). In all these sentences, the highlighted words do not change with the subject or tense, so they are non-finite verbs.

हिंदी में, Non-finite verbs (अपूर्ण क्रिया) वे क्रियाएँ होती हैं जो कर्ता (subject) या समय (tense) के अनुसार नहीं बदलतीं। ये अपने आप मुख्य क्रिया नहीं बन सकतीं और आमतौर पर किसी दूसरी क्रिया के साथ प्रयोग होती हैं। इनके तीन प्रकार होते हैं: Infinitive (to + verb), Gerund (verb + ing), और Participle (तीसरा रूप या ing रूप जो विशेषण की तरह काम करता है)। उदाहरण: “I like to read books.” (यहाँ to read infinitive है), “Reading is fun.” (यह gerund है), और “The broken window needs repair.” (यह participle है)। इन सभी में क्रिया का रूप नहीं बदलता, इसलिए ये non-finite verbs कहलाते हैं।

A verb is finite when it changes according to the subject and tense, and it can be the main verb of a sentence. A non-finite verb does not change with subject or tense and cannot be the main verb alone—it needs support from a finite verb.

For example:

1. She plays cricket. → यहाँ plays subject (she) के अनुसार बदल रहा है, इसलिए यह finite verb है।
2. I want to learn English. → यहाँ want finite verb है, लेकिन to learn non-finite (infinitive) है।
3. Reading books is good. → यहाँ is finite verb है, और reading non-finite (gerund) है।
4. He wrote a letter. → wrote past tense दिखा रहा है, इसलिए यह finite verb है।
5. Written work is important. → यहाँ written non-finite (participle) है, क्योंकि यह adjective की तरह काम कर रहा है और tense नहीं दिखा रहा।

सरल नियम (Easy Trick):

• जो verb tense या subject के साथ बदलता है = Finite Verb
• जो verb नहीं बदलता = Non-finite Verb

इस तरह आप आसानी से पहचान सकते हैं कि कोई verb finite है या non-finite।
