लेखकाचा दृष्टीकोन व आशयसूत्रे यांचा संबंध विशद करा​

Answer:

तुम्ही कोणत्या विषयावर बोलत आहात हे महत्त्वाचे नाही, जेव्हा तुम्ही एखाद्या गोष्टीबद्दल बोलतो तेव्हा तुम्ही त्याकडे एका विशिष्ट दृष्टिकोनातून (POV) पाहता. याचा अर्थ असा होऊ शकतो की तुम्ही विषयाच्या बाजूने आहात, त्याच्या विरोधात आहात किंवा अगदी तटस्थ आहात. ज्याप्रमाणे तुमच्याकडे प्रत्येक गोष्टीसाठी पीओव्ही आहे, त्याचप्रमाणे ग्रंथांचे लेखकही आहेत. विशेषत: गैर-काल्पनिक मजकूरांमध्ये, आपण लेखकाच्या लेखनाच्या विविध पैलूंचा वापर करून ते विषय कसे पाहतात हे निर्धारित करू शकता. या पैलूंमध्ये लेखकाची शब्द निवड, वाक्प्रचार आणि त्यांनी समाविष्ट करण्यासाठी निवडलेली सामग्री समाविष्ट आहे.
