i. I Will vs I Would

1. I Will : I will is used to talk about future actions, decisions, or promises. I will ভৱিষ্যতৰ কাম, সিদ্ধান্ত বা প্ৰতিশ্ৰুতি বুজাবলৈ ব্যৱহাৰ হয়। ইয়াৰ অৰ্থ হৈছে কামটো নিশ্চিতভাৱে হ’ব। Structure: I will + base verb. Examples: i. I will call you later. ii. I will help you with your homework. iii. I will finish this work today.

2. I Would : I would is used to talk about imaginary situations, polite requests, or past habits. I would কাল্পনিক পৰিস্থিতি, ভদ্ৰ অনুৰোধ বা অতীতৰ অভ্যাস বুজাবলৈ ব্যৱহাৰ হয়। ইয়াৰ অৰ্থ হৈছে condition বা কল্পনাৰ ওপৰত নিৰ্ভৰ কৰা কাম। Structure: I would + base verb. Ex: i. I would help you if I had time. ii. I would like a cup of tea. iii. When I was young, I would play outside.

Difference / পাৰ্থক্য : i. I will = Real future or certain decision (নিশ্চিত ভবিষ্যৎ বা সিদ্ধান্ত)। ii. I would = Imaginary, conditional, or polite expression (কাল্পনিক, condition-যুক্ত বা ভদ্ৰ প্ৰকাশ)।

Trick / ট্ৰিক: i. I will = Sure / Future. ii. I would = If / Polite / Imagine.

ii. Has Been vs Have Been

1. Has Been: Used with He, She, It (Singular Subject). Has been একবচন subject-ৰ সৈতে ব্যৱহাৰ হয়। He, She, It থাকিলে has been ব্যৱহাৰ কৰিব লাগে। Structure: Subject + has been + verb-ing/complement. Used in Present Perfect & Present Perfect Continuous Tense. Ex: i. She has been reading. ii. He has been working. iii. It has been raining.

2. Have Been : Used with I, You, We, They (Plural Subject). Have been বহুবচন subject-ৰ সৈতে ব্যৱহাৰ হয়। I, You, We, They থাকিলে have been ব্যৱহাৰ কৰিব লাগে। Structure: Subject + have been + verb-ing/complement. Used in Present Perfect & Present Perfect Continuous Tense. Ex: i. I have been studying. ii. We have been playing. iii. They have been sleeping.

Difference / পাৰ্থক্য : i. Has been → Singular Subject (একবচন), ii. Have been → Plural Subject / I & You (বহুবচন / I & You)

Trick / ট্ৰিক : i. He/She/It → Has been, ii. I/You/We/They → Have been

=================================================================

iii. Should Have vs Would Have

Should Have : Should have is used to talk about past advice, regret, obligation, or something that was the right thing to do but did not happen. Should have অতীতৰ উপদেশ, অনুশোচনা বা কৰ্তব্য বুজাবলৈ ব্যৱহাৰ হয়। ইয়াৰ অৰ্থ হৈছে কামটো কৰা উচিত আছিল কিন্তু কৰা নহ’ল। Structure: Subject + should have + past participle. Examples: i. You should have studied harder. ii. She should have called me earlier. iii. They should have finished the work on time.

Would Have : Would have is used to talk about imaginary or unreal past situations and results that could have happened under certain conditions. Would have কাল্পনিক বা নহোৱা অতীতৰ ফলাফল বুজাবলৈ ব্যৱহাৰ হয়। ইয়াৰ অৰ্থ হৈছে condition পূৰণ হ’লেহেঁতেন কামটো ঘটিলেহেঁতেন। Structure: Subject + would have + past participle. Ex: i. I would have helped you if I had known. ii. She would have passed the exam. iii. They would have come earlier.

Difference / পাৰ্থক্য :  i. Should have = Past advice or regret (কৰা উচিত আছিল)। ii. Would have = Imaginary past result depending on a condition (condition থাকিলে হ’লহেঁতেন)।

Trick  / ট্ৰিক : i. He should have studied = পঢ়া উচিত আছিল। ii. He would have passed = condition থাকিলে পাছ কৰিলেহেঁতেন।

iv. I Have / I've + V3

We use I have / I've + V3 to talk about our experience or something that has happened in our life. I have / I've + V3 জীৱনৰ অভিজ্ঞতা বা ইতিমধ্যে হোৱা কাম বুজাবলৈ ব্যৱহাৰ হয়। Past participle (V3) means the third form of the verb such as eaten, seen, gone, visited. Structure: I have / I've + past participle (V3) + object/place/etc.

Ex: i. I've been to Goa twice. ii. I've already eaten breakfast. iii. I've seen that movie before. iv. I've bought a new phone. v. I've finished my work. vi. I've met her at a party.

Common Mistakes / সাধাৰণ ভুল

Wrong : I have went to the market. : Correct : I have gone to the market. (go → gone)
Wrong : I've go to school. : Correct : I've gone to school. (go → gone)
Wrong : I have eat lunch. : Correct : I have eaten lunch. (eat → eaten)
Wrong : I've seened that film. : Correct : I've seen that film. (see → seen)
Wrong : I have visiteded Delhi. : Correct : I have visited Delhi. (visit → visited)

These are wrong because after have / I've, we must use only the past participle (V3). Have/I've-ৰ পিছত সদায় V3 ব্যৱহাৰ কৰিব লাগে। Ex: go → gone, eat → eaten, see → seen, visit → visited.

Trick  / ট্ৰিক : If you can use “He/She has…”, then you can also use “I have / I've…”. He/She-ৰ সৈতে যি V3 ব্যৱহাৰ হয়, I have / I've-ৰ সৈতেও একেই V3 ব্যৱহাৰ হয়। Examples: He has eaten → I have eaten. She has been there → I've been there. They have visited Paris → I've visited Paris.
