<p>the primary reason for using different characters is to distinguish between actions or events happening in the past (又) and those happening in the present or future (再). This distinction helps convey the temporal aspect of the action and provides clarity in Chinese communication.</p>
<p>又 (Yòu):</p>
<p>Temporal Aspect: &quot;又&quot; is used in the past tense to indicate the repetition of an action or event that occurred before. It emphasizes the continuity or recurrence of an action in the past.

再 (Zài):</p>
<p>Temporal Aspect: &quot;再&quot; is used in the present or future tense to indicate the repetition of an action or event. It emphasizes the idea of doing something again in the present or future.

<p><strong>1. When 又 means &quot;again&quot;, it can be used for something repeated in the past, present, or future.</strong></p>

"If there is a reason for them to be different". No, just common practice. You can not translate both into one English word "again" and come back to ask why the Chinese do not use one word.

Although not all Chinese varieties use the two words 再 vs 又, the *distinction* represented is fairly common across all the Chinese languages, with very few even possessing a merged *'again'* (閣 *koh* in Xiamen Min Nan can do both, but 閣再 *koh-chài* and 又閣 *iū-koh* are also used, observing this distinction).

This may be related to the fact that 再 *zài* in Old Chinese was [strictly limited](https://books.google.com/books/about/Outline_of_Classical_Chinese_Grammar.html?id=viWF1UZqKC8C) to the adverbial meaning 'twice'.

The extension of 再 to a *present/future*-'again' is stated to have happened [during the Tang Dynasty](https://en.wiktionary.org/wiki/%E5%86%8D). I surmise that this is related to the rise of the classifier system in that period, through 再次 'the second time' becoming 'once again'.

Meanwhile, 又 had had an 'even/again/moreover' semantic domain from the Classical period, retained into the majority of Chinese varieties of the present day (in Min Dong it has mostly been supplanted by 復, which had meant 'to return' in the Classical language and did extend to verbal uses of 'again' in Modern Standard Mandarin, much like Latin 're-' in English).

The adverb 亦, often used as 'also', also had meanings corresponding to Modern English 'again' in Classical Chinese, but now this is preserved very sporadically, mostly among Wu varieties.

Note that 还 is also [often considered](https://shs.hal.science/file/index/docid/751182/filename/DonazzanTovenaSemlex07.pdf) a "repetitive adverb" in Modern Standard Mandarin, and so you'll often seen these three discussed in the linguistic literature. Compare the evolution of French *encore*; semantic map models have been developed for these [cross-lingustically](https://link.springer.com/article/10.1186/s40655-017-0024-5), where you will see not all varieties of Chinese fall perfectly along the same lines.

the primary reason for using different characters is to distinguish between actions or events happening in the past (又) and those happening in the present or future (再). This distinction helps convey the temporal aspect of the action and provides clarity in Chinese communication.

又 (Yòu):

Temporal Aspect: "又" is used in the past tense to indicate the repetition of an action or event that occurred before. It emphasizes the continuity or recurrence of an action in the past.
Example: 我又看了这部电影。(Wǒ yòu kàn le zhè bù diànyǐng.) - "I watched this movie again."
再 (Zài):

Temporal Aspect: "再" is used in the present or future tense to indicate the repetition of an action or event. It emphasizes the idea of doing something again in the present or future.
Example: 我会再试一次。(Wǒ huì zài shì yī cì.) - "I will try again."

[Comparing "zai" and "you"](https://resources.allsetlearning.com/chinese/grammar/Comparing_%22zai%22_and_%22you%22)

Both 再 (zài) and 又 (yòu) express the repeating of an action and can be roughly translated in English to "again." However, 再 is used to express actions that have not yet occurred (the "future again") and 又 is used for actions that have already occurred (the "past again"). They're not interchangeable. In addition, each word has a few special usages.
