अगर (agar)

conjunction The everyday Hindi word for 'if,' introducing conditional clauses; almost always paired with तो (to) in the second half of the sentence.
Sense 1 : conditional 'if'
conjunction Sets up an if-clause and is typically completed with तो (to) before the main clause: अगर ... तो (agar ... to).
Synonyms: यदि (yadi, more formal/literary), बशर्ते (basharte, less common, 'provided that')
Frequency: high
Cultural Note: You'll hear अगर...तो (agar...to, 'if...then') constantly in daily bargaining and planning talk in Delhi markets: अगर सस्ता होगा तो ले लूँगा (agar sastaa hogaa to le loongaa, 'if it's cheap, I'll buy it'). यदि (yadi) is the word you will meet in written Hindi or formal speeches, while अगर (agar) is what people actually say at home and on the street.
Common Mistakes: 1) Learners often drop तो (to) entirely; while it can be omitted in casual speech, beginners should practice including it, since native speakers lean on it to signal where the 'then' clause begins. 2) अगर (agar) itself never changes form or agrees with anything -- learners sometimes try to inflect or mark it, but it is a fixed conjunction.
