“Ka” to connect nouns

Let me start with “ka” connecting nouns.

• ka – か : a parallel particle connecting nouns with adding the meaning of “or”.

Japanese native speakers often use this type of “ka” to connect as many nouns as they want or need. In other words, they often use it for polysyndeton like “A ka B ka C ka D”. Let me explain how to use it through the example sentence below.

Example #1: how to connect nouns by “ka”

Below are the new words used in the example sentence.

• watashi – 私 (わたし) : a pronoun meaning ‘I’ in Japanese.
• wa – は : a binding particle working as a case marker or topic marker. In the example, it is put after the pronoun, “watashi”, to make the subject word in the sentence.
• sushi – 寿司 (すし) : a noun meaning ‘sushi’ in Japanese.
• soba – 蕎麦 (そば) : a noun meaning ‘soba noodle’ in Japanese.
• wo – を : a case particle put after a noun or noun phrase to make the object word in a sentence. In the example, it is put after the noun phrase, “sushi ka soba”, to make the object in the sentence.
• tabe -食べ (たべ) : one conjugation of the verb, “taberu”, which means ‘to eat’ in Japanese. In the example, it has been conjugated for the better connection with its following word.
• tai – たい : an auxiliary verb put after a verb to make its desire form. Probably it is well known as a part of Japanese tai form. In the example, it is put after the conjugated verb, “tabe”, to make its desire form, “tabe tai”, which means ‘to want to eat’.

This is a typical usage of this type of “ka”. In this example, it connects the two nouns, “sushi” and “soba”. And the formed phrase contains the meaning of “or”.

As I mentioned above, we can use this particle to connect as many nouns as we want or need. So, three or more nouns can also be linked by this particle. When we want to make parallel expressions in Japanese, this particle is very helpful.

“Ka” to make a question

Then, let me explain the next type of “ka”.

• ka – か : a sentence-ending particle put at the end of a sentence to make a question. Normally this “ka” is used with the pitch raised.

Japanese native speakers quite often use this type of “ka” to make questions. Let me explain how to use it in detail through the example sentence below.

Example #2: how to make a question in Japanese

Below are the new words and particle used in the example sentence.

• anata – あなた : a pronoun meaning ‘you’ in Japanese.
• wa – は : the same as explained in the last example. In this example, it is put after the pronoun, “anata”, to make the subject word in the sentence. But, honestly, it provides the topic simultaneously. It puts a focus on “you”.
• ga – が : a case particle put after a noun to make the subject word or the object word in a sentence. In the example, it is put after the noun, “sushi”, to make the object word in the sentence.
• suki – 好き (すき) : one conjugation of the na-adjective, “sukina”, which means ‘favorite’ in Japanese. But it is quite often used like an individual word to say ‘to like’ or ‘to love’ in Japanese. Actually, in this example, it has been translated as “to like”.
• desu – です : an auxiliary verb put after a noun or adjective to make it polite. Probably it is well known as a part of Japanese desu form. In the example, it is put after “suki” to make it sound polite.

This is a typical usage of this type of “ka”. As its definition suggests, it is put at the end of the example sentence to make the question. In the Japanese language, positions of words can easily be swapped. So changing the positions of a noun and a verb in a sentence doesn’t mean anything. When we want to make questions in Japanese, we need the help of this sentence-ending particle.

“Ka” to express uncertainty

Next, then, let me explain how to express uncertainty with “ka”.

• ka – か : an adverbial particle put after a word, phrase, or clause to express its uncertainty.

The meaning and translation of this type of “ka” can vary widely depending on the situation, context, and words used together with it. Here, let me focus on one of the most popular usages.

Example #3: how to make an “if” clause

Below are the new words and particle used in the example sentence.

• ashita – 明日 (あした) : a noun meaning ‘tomorrow’ in Japanese. It is a noun, but can also be used like an adverb and inserted almost anywhere in a sentence to say “tomorrow”. In this example, it is used as an adverb.
• ame – 雨 (あめ) : a noun meaning ‘rain’ in Japanese.
• ga – が : the same as explained in the last example. In this example, it is put after the noun, “ame”, to make the subject word in the clause.
• furu – 降る (ふる) : a verb meaning ‘to fall’ in Japanese.
• wakara – 分から (わから) : one conjugation of the verb, “wakaru”, which means ‘to see’ or ‘to understand’ in Japanese. In the example, it has been conjugated for the better connection with the following word.
• nai – ない : an auxiliary verb put after a verb or adjective to deny its meaning. In the example, it is put after the conjugated verb, “wakara”, to deny its meaning.

This is a typical usage of this type of “ka”. In this example, it works after “ashita ame ga furu” to make the noun clause with adding the meaning of “if”, with expressing the uncertainty. When we want to make “if” clauses in Japanese, this “ka” would be helpful in many cases. But, these “if” clauses should be noun clauses.

“Ka” to show understanding

Next, let me explain “ka” to show understanding.

• ka – か : a sentence-ending particle put at the end of a sentence to show understanding or agreement softly.

Unlike the one to make a question, this type of “ka” is not used with the pitch raised. Let me explain how to use it through the example sentence below.

Example #4: how to show understanding by “ka”

Below are the new words used in the example sentence.

• kinou – 昨日 (きのう) : a noun meaning ‘yesterday’ in Japanese. It is a noun, but can also be used like an adverb and inserted almost anywhere in a sentence to say “yesterday”. In this example, it is used as a noun.
• wa – は : the same as explained in the last examples. In this example, it works as a topic marker after the noun, “kinou”, to put a focus on “yesterday”.
• yuki – 雪 (ゆき) : a noun meaning ‘snow’ in Japanese.
• deshi – でし : one conjugation of the auxiliary verb, “desu”, which is put after a noun or adjective to make it polite. In this example, it has been conjugated for the better connection with its following word.
• ta – た : an auxiliary verb put after a verb, adjective, auxiliary verb, or phrase to make its past tense form. In the example, it is put after the conjugated auxiliary verb, “deshi”, to make its past tense.

This is a typical usage of this type of “ka”. Again, but it is not used with the pitch raised.

Honestly, translating this “ka” into English is quite difficult. But I added the interjection, “ah”, into the English sentence to reflect a piece of the original nuance. Their roles are not really the same, but not so different, I think. “Ka” can be used to show understanding or agreement softly, perhaps more softly than “ah” does.

“Ka” to make a suggestion

Lastly, let me explain “ka” to make a suggestion.

• ka – か : a sentence-ending particle put at the end of a sentence to make a suggestion.

This “ka” is similar to the last one. But the pitch of this “ka” varies depending on the situation. Sometimes the pitch is raised like the one to make a question and sometimes not. It depends on the way of suggesting.

Let me explain how to use this “ka” through the example sentence below.

Example #5: how to make a suggestion by “ka”

Below are the new words used in the example sentence.

• raishuu – 来週 (らいしゅう) : a noun meaning ‘next week’ in Japanese. It is a noun, but can also be used like an adverb and inserted almost anywhere in a sentence to say “next week”. In this example, it is used as an adverb.
• kyoto – 京都 (きょうと) : one of the most famous cities in Japan. It is a noun.
• ni – に : a case particle used to indicate an object to which someone or something goes. In the example, it is put after the noun, “kyoto”, to indicate the particular place to which they go.
• iko – 行こ (いこ) : one conjugation of the verb, “iku”, which means ‘to go’ in Japanese. It has been conjugated for the better connection with its following word.
• u – う : an auxiliary verb put after a verb to make a suggestion. In this example, it is put after the conjugated verb, “iko”, to say “let’s go” in Japanese.

This is a typical usage of this type of “ka”. In this example, it is put after the verb phrase, “iko u”, to make the suggestion.
