Voice change

সাধারণ অ‡_© Voice কণ্ঠস্বর। ব্যাকরণে একে বলা হয় বাচ্য। Verb এর যে Form দ্বারা কর্তা যখন কাজটি নিজে করে বা অন্যের মাধ্যমে সম্পাদন করিয়ে নেয় এবং কZ©vi সঙ্গে কাজের সম্পর্ক দেখায় এবং এইভাবে Verb- এর রূপের যে পরিবর্তন ঘটে তাকে Voice বলে। যেমন:
a. He has made a basket.
b. A basket has been made by him.

ওপরের প্রথম বাক্যে কর্তা নিজে কাজ করেছে এবং দ্বিতীয় বাক্যে কর্তার ওপর কাজ করানো হয়েছে।
(i) Verb এর object –টি Subject হিসেবে প্রথমে বসেছে।
(ii)
সাহায্যকারী verb-টি বসেছে।
(iii)
অতিরিক্ত একটি be verb বসেছে।
(iv) verb 
এর Past Participle Form ব্যবহূত হয়েছে।
(v) extension
বসেছে।
(vi) Preposition by
বসেছে।
(vii) Verb এর subject-টি object হয়েছে।

Voice সাধারণত দুই প্রকার। যথা

1. Active voice (সক্রিয় বাচ্য) এবং 2. Passive voice (নিষ্ক্রিয় বাচ্য)

1.       Active voice: কর্তা নিজেই কাজ করে অর্থাৎ কর্তা সক্রিয় এরূপ বোঝালে verb-এর Active voice হয়।যেমন: উপরের বক্সে আমরা দেখতে পাচ্ছি Active বাক্যে কর্তা  অর্থাৎ subject নিজেই কাজটি সম্পাদন করেছে।

2.       Passive voice: Verb-এর যে form দ্বারা কর্তা নিজে কাজ সম্পাদন করে না, বরং কাজটি অন্যের দ্বারা করানো হয় এরূপ বোঝায় তাকে Passive voice বলা হয়। যেমন:
Voice change করার সময় বাক্যের Subject Object সম্পর্কে পরিষ্কার জ্ঞান থাকতে হবে। নিচের ছক অনুযায়ী এদের পরিবর্তন হয়ে থাকে। যেমন:
(a)        কোনো কোনো ক্ষেত্রে Active voice-এ দুটি Object-এর মধ্যে যেকোনো একটির পূর্বে Preposition থাকে। এ ধরনের বাক্যে যে Object-টির পূর্বে Preposition থাকে সেই Object-টি Passive voice –এর Subject হিসেবে ব্যবহৃত হয় না। সঙ্গের দ্বিতীয় Object-টি Passive voice –এর Subject হিসেবে বসে।
Active : She did for me the necessary things.
Passive : The necessary things were done for me by her.

(b)        আবার কোনো কোনো সময় Active voice-এর দুটি Object থাকে। সেক্ষেত্রে উক্ত Active Voice-কে Passive voice করার সময় প্রথম Object-টি অর্থাৎ ব্যক্তিবাচক Object-টিকে Subject করাই উত্তম।
Active : The Headmaster teaches us English.
Passive : We are taught English by the headmaster.
    Or,      English is taught us by the headmaster.
উল্লিখিত বাক্যটিতে লক্ষ করলে দেখা যায়, Active voice-টিতে teaches মূল verb-টির পরে দুটি Object যথাক্রমে us English আছে। এর মধ্যে us ব্যক্তিবাচক Object হওয়ায় তাকে Passive voice-এর Subject হিসেবে বসানো হয়েছে।

Tense অনুযায়ী Auxiliary verb ব্যবহার করার নিয়ম:

Present Indefinite:     am /is /are
Past Indefinite:          was /were
Future Indefinite:      shall be /will be
