इसीलिए (isiilie)
conjunction
A single-sense connective meaning 'that is why / for this very reason' -- an emphatic version of इसलिए (islie), built by adding the emphatic particle ही (hii) into the middle of that word.
Sense
1
:
that is why, for this very reason
conjunction Typically opens the result clause of a cause-result sentence, often picking up a क्योंकि (kyonki) clause that came before it: क्योंकि बारिश हो रही थी, इसीलिए मैं देर से आया (kyonki baarish ho rahii thii, isiilie main der se aayaa, 'because it was raining, that's why I came late').
Synonyms: इसलिए (islie), इस वजह से (is vajah se), इस कारण (is kaaran, slightly formal)
Frequency: high
Cultural Note: Think of इसीलिए (isiilie) as इसलिए (islie) with a finger pointed at the reason -- the embedded ही (hii) is the same emphatic particle you hear in यही (yahii, 'this very one') or वही (vahii, 'that very one'). You'll hear it a lot in everyday storytelling, when someone wants to underline that a particular reason, and no other, explains what happened.
Common Mistakes: 1) Learners often use इसलिए (islie) and इसीलिए (isiilie) interchangeably, but इसीलिए (isiilie) carries an added punch of emphasis -- closer to 'that is exactly why' -- so overusing it in neutral explanations can sound overly dramatic. 2) Don't confuse this with इसलिए कि (islie ki), which means 'because' (introducing a reason), not 'that is why' (introducing a result).
