The Japanese language

Japanese is a language, originally spoken by over a 120 million speakers in Japan. Japanese has a mysterious aura around it, although it is believed to be related to languages such as Korean and possibly even Turkish (however, it is notable that oftentimes such relatedness is traced not to same historical origins but to a phenomenon known as Sprachbund). Japanese has undergone multiple periods of evolution, which roughly correspond with periods of Japanese history (including a period where the country's borders were closed). In the latest period, Japanese has been characterised by the fast adoption of foreign (especially English) terminology into its own vocabulary, preceded by a simplification of its writing system.

Japanese is written in three different native writing systems, and a non-native one. It has Kanji hieroglyphs, the Hiragana syllabry (used for writing Japanese words and also endings to Kanji) and the Katakana syllabry (used for writing loanwords). There are also systems for transcribing this into the Latin alphabet, the most famous of which is one called Romaji. CoolJugator tries to, whenever relevant, use all four of these writing systems, at the very least providing a version in the native writing system and a Romaji rendering.

About Japanese conjugation

Japanese conjugation is a procedure in which Japanese verbs are changed to match with various other features of the phrase and its context. In Japanese, even adjectives are conjugated. A number of basic stem forms exist, out of which other forms are derived:

  • the imperfective stem - the stem out of which the plain present negative form is derived
  • the continuative stem - a steam used to denote a continuous action
  • the terminal stem - the stem which is used in certain contexts when the verb attaches to other words in the sentence
  • the attributive stem - a stem similar to the hypothetical stem, used for attaching the word to other words in the sentence and often identical to it
  • the hypothetical stem - a stem used to express potential or hypothetical ideas
  • the imperative stem - the stem used for expressing commands

In Japanese, you can conjugate verbs by factors such as:

  • tense - Japanese has present, past tenses
  • voice - active and passive: the difference between 'something is doing' and 'something is being done'
  • politeness level - separate conjugations exist for plain and polite verb forms
  • negativity - conjugation depends on whether it is a positive or a negative statement
  • aspect - which connect the Japanese verb to the flow of time, that is, they indicate whether an action is occuring at the time, used to occur frequently, or occurred generally
  • mood - indicates the speaker's atitude, and is distinguished between e.g. indicative (a statement), imperative (command or request).

In the Japanese CoolJugator, as usually in CoolJugators, we try to provide you as much information about the verb as possible, although we also try to focus on the most important aspects of conjugation. We hope that this conjugation information, next to the abundant examples we provide, will help you become a better Portuguese speaker, or just learn more about the language, or both.
