हिंदी व्याकरण में शब्दों को उनके रूप बदलने के आधार पर दो भागों में बांटा जाता है: विकारी और अविकारी।
अविकारी शब्द वे शब्द होते हैं जिनका रूप लिंग, वचन, पुरुष या कारक के अनुसार नहीं बदलता। यानी इन शब्दों का रूप हमेशा एक जैसा रहता है।
अविकारी शब्दों के मुख्य प्रकार इस प्रकार हैं:
1. क्रिया विशेषण: जैसे: बहुत, जल्दी, धीरे
2. सम्बन्धबोधक (Postposition): जैसे: के, से, में, पर
3. समुच्चयबोधक: जैसे: और, लेकिन, क्योंकि
4. विस्मयादिबोधक: जैसे: अरे!, वाह!, ओह!
ये शब्द वाक्य में अलग-अलग अर्थ और संबंध दिखाते हैं, लेकिन इनका रूप नहीं बदलता। अविकारी शब्द भाषा को स्पष्ट और प्रभावी बनाने में महत्वपूर्ण भूमिका निभाते हैं, क्योंकि ये बिना बदले अर्थ को जोड़ने और व्यक्त करने का काम करते हैं।
Answered By Dr. Aarav Gupta
Bridging clinical medicine and everyday wellness — helping readers make informed decisions about their health and appearance.Dr. Aarav Gupta is a practising physician with over 8 years of clinical experience, specialising in general medicine and dermatology-adjacent wellness. He holds an MBBS from All India Institute of Medical Sciences (AIIMS), New Delhi, and an MD in General Medicine from the same institution — credentials that place his health and beauty writing on a foundation of verified medical knowledge. His content covers evidence-based skincare, preventive health, nutrition, mental wellness, and the science behind beauty trends that are too often reported without clinical context. His work has been published on platforms including HealthShots, OnlyMyHealth, and Lybrate, where he contributes medical reviews, explainers, and practical health guidance grounded in current clinical evidence. With 8+ years of patient-facing practice behind his writing, Dr. Gupta brings a perspective that is rarely found in health and beauty content — one shaped by real clinical encounters, not just research papers. He is a registered member of the Indian Medical Association (IMA) and has spoken on health literacy and responsible medical communication at platforms including the India Health Summit. Across all his work, his standard remains consistent — every claim is grounded in medical evidence, every recommendation is one he would make to a patient, and no trend is reported without clinical scrutiny.
