ヒントとコツ (3)

💡

Focus on the -e

Always check if your verb ends in -e before adding thakbo. It's the most common error.

💡

Use 'By'

Always use 'by' (নাগাদ/মধ্যে) to make the future perfect clear.

The 'Guess' Trick

Review Summary

  • [Verb Stem + e] + [Future of thaka]
  • [Time] + এর মধ্যে (er moddhe) + Future Perfect

よくある間違い

The first sentence is Simple Future ('I will do'). Use the Future Perfect to emphasize completion by a deadline.

Wrong: আমি আগামীকাল কাজটা করব। (Ami agamikal kajta korbo.)
正解: আমি আগামীকালের মধ্যে কাজটা করে থাকব। (Ami agamikal-er moddhe kajta kore thakbo.)

In Bengali, Future Perfect is often used for 'Assumed Past' (He must have gone). Context is key to distinguish between 'He will have finished' and 'He probably finished'.

Wrong: সে গিয়ে থাকবে না। (Se giye thakbe na.) [Used when they mean 'He might not have gone']
正解: সে গিয়ে থাকবে না। (Correct form, but often confused with probability)

The negative particle 'na' must follow the auxiliary verb 'thakbo', not come between the participle and the auxiliary.

Wrong: আমি করে না থাকব। (Ami kore na thakbo.)
正解: আমি করে থাকব না। (Ami kore thakbo na.)

Next Steps
