A polite sentence ending that expresses respect toward the listener.

The nuance

Attach -(아)요 or -(어)요 to the verb/adjective stem depending on the last vowel. If the stem ends with 아 or 오 without a final consonant, use -(아)요; otherwise, use -(어)요. The verb 하다 changes to 해요.

Real-world examples

  • 가다 → 가요

    ga-da → ga-yo, ga da → ga yo

    The stem '가' ends with 아, so attach '-아요'.

  • 먹다 → 먹어요

    meok-da → meok-eo-yo, meok da → meok eo yo

    The stem '먹' does not end with 아 or 오, so attach '-어요'.

  • 하다 → 해요

    ha-da → hae-yo, ha da → hae yo

    The verb 하다 is irregular and changes to '-해요'.

  • 가다 → 가어요

    ga-da → ga-eo-yo, ga da → ga eo yo

    Since '가다' ends with 아 or 오, use '-아요'. '-가어요' is incorrect.

  • 먹다 → 먹아요

    meok-da → meok-a-yo, meok da → meok a yo

    '먹다' does not end with 아 or 오, so use '-어요'. '-먹아요' is incorrect.
