The Dative Suffix -ku and its Euphonic Changes

Grammar Rule in 30 Seconds

The suffix '-ku' (or '-ukku') acts like 'to' in English, indicating direction, purpose, or a recipient.

  • Add '-ku' to nouns ending in vowels, e.g., 'veedu' (house) becomes 'veettukku' (to the house).
  • Add '-ukku' to most consonant-ending nouns, e.g., 'maram' (tree) becomes 'marathukku' (to the tree).
  • Use it for destinations, recipients of actions, or expressing 'for' in terms of purpose.
Noun + (euphonic change) + ku = Destination/Recipient

Perguntas frequentes (8)

It's a sandhi rule. Nouns ending in '-am' change to '-ath-' before adding the dative suffix to make it easier to pronounce.

Sometimes, but usually -ku is for space and recipients. For time, we use other markers.

Mostly, but it can also mean 'for' or 'because of' depending on the verb.

Vowel-ending nouns usually take -ku; consonant-ending nouns usually take -ukku.

Pronouns are irregular in Tamil. 'Naan' (I) becomes 'enakku' (to me) as a fixed form.

Yes, it is the standard way to mark the indirect object (the person receiving something).

Sometimes, but it's better to keep it for clarity. Dropping it might make you sound like a child.

You will change the meaning from 'I am going to the house' to 'I am in the house'.
