Translation and Meaning of: 時速 - jisoku

The Japanese word 時速[じそく] is a common term that appears in various everyday contexts, especially when the subject is speed. If you've ever wondered what it exactly means or how to use it correctly, this article will clarify everything. Let's explore its meaning, origin, writing in kanji, and even practical tips for memorization. Additionally, we will see how this word is perceived in the Japanese language and in what situations it is commonly employed.

Whether for Japanese students or simply curious about the language, understanding 時速 can be useful both in travel and while consuming Japanese media. Here at Suki Nihongo, our goal is to provide clear and precise explanations, so let’s get straight to the point without beating around the bush. You will discover, for example, why this word is so common in traffic news and how to differentiate it from similar terms.

Meaning and use of 時速

The term 時速 [じそく] literally means "speed per hour" and is used to indicate the measurement of kilometers per hour (km/h) or other similar units. Unlike 速度 [そくど], which refers to speed in general, 時速 specifies the temporal measurement. For example, when saying "この車の時速は100キロです" (This car is at 100 km/h), it is clear that it refers to a measure per hour.

This word is frequently found in contexts such as traffic, speed sports, and even in weather forecasts. An interesting detail is that, although it is a technical term, it is widely understood by the general public. This happens because Japan has a culture that is very oriented towards precision, especially in transportation and logistics.

Origin and writing in kanji

The composition of 時速 comes from the kanjis 時 (hour, time) and 速 (speed, fast). Together, they form a word that exactly conveys the idea of "speed measured by hour". It is worth noting that 速 alone already carries the sense of quickness, but when combined with 時, it gains a more specific meaning.

It is important to note that 時速 does not have significant dialectal variations in Japan, being understood in the same way in all regions. Furthermore, unlike some Japanese words that have changed meaning over the centuries, 時速 has maintained its original definition since its adoption into the language.

Tips for memorizing and using correctly

An effective way to memorize 時速 is to associate it with everyday situations. For example, think of traffic signs or the speedometer of a car, where this measurement appears constantly. Another tip is to create flashcards with sentences like "新幹線の時速は約300キロです" (The speed of the Shinkansen is approximately 300 km/h).

Moreover, be careful not to confuse 時速 with similar terms such as 秒速 (meters per second) or 分速 (meters per minute). These words follow the same construction logic but refer to different time intervals. Knowing how to differentiate them can prevent mistakes in conversations or more technical texts.
