Definition and meanings of “shitsukoi”

Let me start with the definition and meanings of “shitsukoi”.

• shitsukoi – しつこい : an i-adjective meaning ‘insistent’ or ‘persistent’ in Japanese.

Japanese native speakers use this i-adjective often to describe someone who does not stop doing something annoying. However, they sometimes use this in a good way: to describe someone who keeps working on something difficult.

The definition and meanings are not that difficult, I think. Then, let me explain how to use this i-adjective through the example sentence below.

Example #1: how to say “insistent” in Japanese

Below are the new words used in the example sentence.

• kare – 彼 (かれ) : a pronoun meaning ‘he’ in Japanese.
• wa – は : a binding particle working as a case marker or topic marker. In the example, this works after “kare” to make the subject in the sentence.
• totemo – とても : an adverb of degree meaning ‘very’, ‘much’, ‘so’, or such in Japanese. In the example, this works before “shitsukoi” to emphasize its meaning.

This is a typical usage of “shitsukoi”. In this example, it works as the complement in the sentence. Like other adjectives, however, it can also work as a modifier in front of a noun. It’s worth knowing, I think.

So far, I’ve explained the definition and meanings of “shitsukoi” and how to use it through the example sentence. In the rest part of this blog post, I will explain its major conjugations. The first one is “shitsukokunai”.

• nai – ない : an auxiliary verb used after a verb, adjective, or auxiliary verb to deny its meaning. Word orders in Japanese and English are different, but the role of this auxiliary verb is similar to that of “not”.

From these two parts, we can understand that “shitsukokunai” is literally the nai form of “shitsukoi” and means ‘not insistent’ or ‘not persistent’ in Japanese. Then, let me explain how to use this form through the example sentence below.

• te – て : the same as used in “shitsukokute”. In the example, this is used after “oshie” to make its te form, “oshie te”. Verbs need to be changed to their te forms to be connected with “kudasai”.
• kudasai – ください : one conjugation of the verb, “kudasaru”, which means ‘to give’ or such in Japanese. When this follows a verb, however, this can work like an auxiliary verb to add the meaning of ‘please’.
