Greek orthography has used a variety of diacritics starting in the Hellenistic period. The more complex polytonic orthography (Greek: πολυτονικό σύστημα γραφής, romanized: polytonikó sýstīma grafī́s), which includes five diacritics, notates Ancient Greek phonology. The simpler monotonic orthography (Greek: μονοτονικό σύστημα γραφής, romanized: monotonikó sýstīma grafīs), introduced in 1982, corresponds to Modern Greek phonology, and requires only two diacritics.
Polytonic orthography (from Ancient Greek πολύς (polýs) 'much, many', and τόνος (tónos) 'accent') is the standard system for Ancient Greek and Medieval Greek. The acute accent (´), the circumflex (ˆ), and the grave accent (`) indicate different kinds of pitch accent. The rough breathing (῾) indicates the presence of the /h/ sound before a letter, while the smooth breathing (᾿) indicates the absence of /h/.
Since in Modern Greek the pitch accent has been replaced by a dynamic accent (stress), and /h/ was lost, most polytonic diacritics have no phonetic significance, and merely reveal the underlying Ancient Greek etymology.
Monotonic orthography (from Ancient Greek μόνος (mónos) 'single', and τόνος (tónos) 'accent') is the standard system for Modern Greek. It retains two diacritics: a single accent or tonos (΄) that indicates stress, and the diaeresis ( ¨ ), which usually indicates a hiatus but occasionally indicates a diphthong: compare modern Greek παϊδάκια (/paiðakia/, "lamb chops"), with a diphthong, and παιδάκια (/peˈðakia/, "little children") with a simple vowel. A tonos and a diaeresis can be combined on a single vowel to indicate a stressed vowel after a hiatus, as in the verb ταΐζω (/taˈizo/, "I feed").
Although it is not a diacritic, the hypodiastole (comma) has in a similar way the function of a sound-changing diacritic in a handful of Greek words, principally distinguishing ό,τι (ó,ti, "whatever") from ότι (óti, "that").[出典:Wikipedia]


is a unique Greek letter that is seldom used in modern literature, but when it appears, it adds a certain gravitas to the text. Its use is particularly apt when describing something that is difficult to understand, perhaps something that is shrouded in mystery or operates beyond the normal bounds of human comprehension. One example of such a thing might be the concept of time travel. While it is a popular theme in science fiction, the idea of being able to travel through time remains firmly entrenched in the 'what if?' realm of the hypothetical. However, as many physicists will attest, the laws of physics do not necessarily preclude the possibility. This is where the letter comes into play. It can be used to add an air of uncertainty or ambiguity to the discussion, indicating that while we may speculate about the feasibility of time travel, ultimately, we are still grappling with a concept that is beyond our full understanding. In a similar vein, the letter could also be used to describe the nature of consciousness. As humans, we experience consciousness every moment of our lives, and yet, we have an incomplete understanding of what it truly means to be aware, to think, and to feel. Philosophers, psychologists, and scientists have all tried to elucidate the mysteries of consciousness, with varying degrees of success. The letter could be brought in to emphasize the notion that while we may have some grasp of what consciousness is, ultimately, it remains a concept that is difficult to pin down and define fully. Whether discussing time travel, consciousness, or any other topic that challenges our comprehension, the letter provides a perfect tool for highlighting the inherent uncertainty and mystery that surrounds these topics. As we continue to explore the limits of human understanding, it is likely that this letter will continue to play a role in our efforts to express the inexplicable.
