There is more to the particle 이나, my previous post deals with this particle as used in numeric expressions. This particle is added at the end of the word which requires generalization, 이나 (ina) for consonant ending words and drops 이 (i) when added to vowel ending words.
Here are some of its uses as generalizer; mostly are question word:
and here are some of its practical applications:
- Question: 누구를 부를까요? (Nugureul bureulkkayo? / Whom shall we invite?)
- Answer: 누구나 좋아요. (Nuguna chuayo. /Anybody is fine.)
- Question: 주말에 어디에 갈까요? (Chumare odi.e kalkkeyo?; Where shall we go this weekend?)
- Answer: 어디나 좋아요 (Odina chuayo. /Anywhere is fine. )
Since 이나 is a particle, that it is attached to a word without a pause, the rules in pronunciation applies. Notice how 무엇 (mueot) became mueoshina when it became 무엇이나 at the first cell of the table above, see also last cell.
