எந

In a sentence

• என்னுடைய நண்பர் ராமன்.

  My friend is Raman.

  Here, 'என்னுடைய' (en-nudaiya) indicates possession, where 'எந' forms the root for the possessive pronoun.

• எந்த புத்தகம் நீங்கள் விரும்புகிறீர்கள்?

  Which book do you like?

  In this sentence, 'எந்த' uses 'எந' as the root for interrogative pronouns addressing choice or options.

• என்னைப் புரிந்துகொள்ள முயலுங்கள்.

  Try to understand me.

  In 'என்னை', the root 'எந' transforms into its accusative case to represent the object of the sentence.
