Zero and First Conditional
Zero and First Conditional (শূন্য ও প্রথম শর্তবাচক বাক্য)
Introductionভূমিকা
Conditional sentences talk about 'if' — what happens when a condition is met. The zero conditional describes facts that are always true, and the first conditional describes a real, likely result in the future. Both are everyday English you will use constantly.
Conditional বাক্য 'if' নিয়ে কথা বলে — কোনো শর্ত পূরণ হলে কী হয়। Zero conditional সবসময় সত্য এমন বিষয় বোঝায়, আর first conditional ভবিষ্যতের বাস্তব ও সম্ভাব্য ফলাফল বোঝায়। দুটোই প্রতিদিনের ইংরেজি, যা আপনি বারবার ব্যবহার করবেন।
Definitionসংজ্ঞা
Zero conditional: if + present simple, present simple (facts). First conditional: if + present simple, will + base verb (a real future result).
Zero conditional: if + present simple, present simple (সত্য/নিয়ম)। First conditional: if + present simple, will + verb (ভবিষ্যতের বাস্তব ফল)।
Bangla Explanationবাংলা ব্যাখ্যা
Zero conditional গঠন: If + present simple, present simple। এটি এমন সত্য বোঝায় যা সবসময় ঘটে — বিজ্ঞান, নিয়ম বা অভ্যাস। যেমন 'If you heat ice, it melts.' এখানে দুই অংশেই present tense। First conditional গঠন: If + present simple, subject + will + verb (base form)। এটি ভবিষ্যতের বাস্তব ও সম্ভাব্য পরিস্থিতি বোঝায়। যেমন 'If it rains, we will stay home.' গুরুত্বপূর্ণ নিয়ম: if-অংশে (condition) কখনো 'will' বসে না — এখানে present tense থাকে; 'will' শুধু ফল-অংশে (result) বসে। if-অংশ আগে থাকলে মাঝে comma দিন; result আগে থাকলে comma লাগে না — 'We will stay home if it rains.'

Common Mistakesসাধারণ ভুল
If it will rain, we will stay home.
If it rains, we will stay home.
Never use 'will' in the if-clause; the condition takes the present simple.
If you will heat ice, it melts.
If you heat ice, it melts.
For a general fact (zero conditional), both clauses use the present simple.
If you study hard, you pass the exam. (meaning a future result)
If you study hard, you will pass the exam.
For a real future result (first conditional), the result clause needs 'will'.
If it rains we will stay home. (no comma)
If it rains, we will stay home.
When the if-clause comes first, put a comma before the result clause.
Tipsটিপস
- Use the zero conditional for facts and rules; use the first conditional for real future possibilities. — সত্য ও নিয়মের জন্য zero conditional; ভবিষ্যতের বাস্তব সম্ভাবনার জন্য first conditional ব্যবহার করুন।
- Keep the if-clause in the present simple — 'will' only ever appears in the result clause. — if-অংশ present simple-এ রাখুন — 'will' শুধু result-অংশে বসে।
- You can swap the order: 'result + if-clause' needs no comma; 'if-clause + result' needs one. — ক্রম বদলানো যায়: 'result + if' হলে comma লাগে না; 'if + result' হলে comma লাগে।

What is the difference between the zero and first conditional?
The zero conditional states facts that are always true (both clauses present simple); the first conditional describes a real, likely future result (if + present, will + verb).
Can I use 'will' after 'if'?
No. In these conditionals the if-clause always uses the present simple. 'Will' belongs only in the result clause.
Do I always need a comma?
Only when the if-clause comes first: 'If it rains, we stay in.' If the result comes first, no comma is needed: 'We stay in if it rains.'
