Question Words And The Japanese Particle, “ka”
The Japanese particle ka (か) is also a useful little syllable. You can think of ka as being the English question mark, or “?”. Adding the syllable ka (か)changes the meaning of the question words, “Who”, “What”, “Where” ,”When”, and “How many”.
The following constructions use a Japanese question word + ka (か):
dare + ka, dareka –
who + ?, someone
nani + ka, nanika –
what + ?, something
doko + ka, dokoka –
where + ?, somewhere
itsu + ka, itsuka –
when + ?, sometime
nannin + ka, nanninka –
how many people + ?, some amount of people
Again, the particle ka (か), can be thought of as the English equivalent of the question mark or, ?, and it turns question words into some other things.
