Fifty is the smallest number that is the sum of two non-zero square numbers in two distinct ways. [1] 50 is a Stirling number of the first kind and a Narayana number.
An alphabet is a standard set of letters written to represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments that can distinguish one word from another in a given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographies assign symbols to words, morphemes, or other semantic units.
A number is a mathematical object used to count, measure, and label. The most basic examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can be represented by symbols, called numerals; for example, "5" is a numeral that represents the number five. As only a relatively small number of symbols can be memorized, basic numerals are commonly organized in a numeral system, which is an organized way to represent any number. The most common numeral system is the Hindu–Arabic numeral system, which allows for the representation of any non-negative integer using a combination of ten fundamental numeric symbols, called digits. In addition to their use in counting and measuring, numerals are often used for labels, for ordering, and for codes. In common usage, a numeral is not clearly distinguished from the number that it represents.
A phoneme is any set of similar speech sounds that is perceptually regarded by the speakers of a language as a single basic sound—a smallest possible phonetic unit—that helps distinguish one word from another. All languages contain phonemes, and all spoken languages include both consonant and vowel phonemes. Phonemes are primarily studied under the branch of linguistics known as phonology.
The Sinhala script, also known as Sinhalese script, is a writing system used by the Sinhalese people and most Sri Lankans in Sri Lanka and elsewhere to write the Sinhala language as well as the liturgical languages Pali and Sanskrit. The Sinhalese Akṣara Mālāva, one of the Brahmic scripts, is a descendant of the Ancient Indian Brahmi script. It is also related to the Grantha script.
The Japanese numerals are numerals that are used in Japanese. In writing, they are the same as the Chinese numerals, and large numbers follow the Chinese style of grouping by 10,000. Two pronunciations are used: the Sino-Japanese (on'yomi) readings of the Chinese characters and the Japanese yamato kotoba.
Anusvara, also known as Bindu, is a symbol used in many Indic scripts to mark a type of nasal sound, typically transliterated ⟨ṃ⟩ or ⟨ṁ⟩ in standards like ISO 15919 and IAST. Depending on its location in the word and the language for which it is used, its exact pronunciation can vary. In the context of ancient Sanskrit, anusvara is the name of the particular nasal sound itself, regardless of written representation.
42 (forty-two) is the natural number that follows 41 and precedes 43.
70 (seventy) is the natural number following 69 and preceding 71.
The Tamil script is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, Singapore and elsewhere to write the Tamil language. It is one of the official scripts of the Indian Republic. Certain minority languages such as Saurashtra, Badaga, Irula and Paniya are also written in the Tamil script.
The Assamese alphabet is a writing system of the Assamese language and is a part of the Bengali-Assamese script. This script was also used in Assam and nearby regions for Sanskrit as well as other languages such as Bodo, Khasi, Mising, Jaintia etc. The current form of the script has seen continuous development from the 5th-century Umachal/Nagajari-Khanikargaon rock inscriptions written in an eastern variety of the Gupta script, adopting significant traits from the Siddhaṃ script in the 7th century. By the 17th century three styles of Assamese alphabets could be identified that converged to the standard script following typesetting required for printing. The present standard is identical to the Bengali alphabet except for two letters, ৰ (ro) and ৱ (vo); and the letter ক্ষ (khya) has evolved into an individual consonant by itself with its own phonetic quality whereas in the Bengali alphabet it is a conjunct of two letters.
The Attic numerals are a symbolic number notation used by the ancient Greeks. They were also known as Herodianic numerals because they were first described in a 2nd-century manuscript by Herodian; or as acrophonic numerals because the basic symbols derive from the first letters of the (ancient) Greek words that the symbols represented.
In the Japanese language, the gojūon (五十音, Japanese pronunciation:[ɡo(d)ʑɯꜜːoɴ], lit. "fifty sounds") is a traditional system ordering kana characters by their component phonemes, roughly analogous to alphabetical order. The "fifty" (gojū) in its name refers to the 5×10 grid in which the characters are displayed. Each kana, which may be a hiragana or katakana character, corresponds to one sound in Japanese. As depicted at the right using hiragana characters, the sequence begins with あ (a), い (i), う (u), え (e), お (o), then continues with か (ka), き (ki), く (ku), け (ke), こ (ko), and so on and so forth for a total of ten rows of five columns.
Proto-Indo-Iranian, also called Proto-Indo-Iranic or Proto-Aryan, is the reconstructed proto-language of the Indo-Iranian branch of Indo-European. Its speakers, the hypothetical Proto-Indo-Iranians, are assumed to have lived in the late 3rd millennium BC, and are often connected with the Sintashta culture of the Eurasian Steppe and the early Andronovo archaeological horizon.
The grammar of the Sanskrit language has a complex verbal system, rich nominal declension, and extensive use of compound nouns. It was studied and codified by Sanskrit grammarians from the later Vedic period, culminating in the Pāṇinian grammar of the 4th century BCE.
Āryabhaṭa numeration is an alphasyllabic numeral system based on Sanskrit phonemes. It was introduced in the early 6th century in India by Āryabhaṭa, in the first chapter titled Gītika Padam of his Aryabhatiya. It attributes a numerical value to each syllable of the form consonant+vowel possible in Sanskrit phonology, from ka = 1 up to hau = 1018.
The Aṣṭādhyāyī is a grammar text that describes a form of the Sanskrit language.
The phonology of the Proto-Indo-European language (PIE) has been reconstructed by linguists, based on the similarities and differences among current and extinct Indo-European languages. Because PIE was not written, linguists must rely on the evidence of its earliest attested descendants, such as Hittite, Sanskrit, Ancient Greek, and Latin, to reconstruct its phonology.
Rinconada Bikol or simply Rinconada, spoken in the province of Camarines Sur, Philippines, is one of several languages that compose the Inland Bikol group of the Bikol macrolanguage. It belongs to the Austronesian language family that also includes most Philippine languages, the Formosan languages of Taiwanese aborigines, Malay, the Polynesian languages and Malagasy.
The Bengali script or Bangla alphabet is the alphabet used to write the Bengali language based on the Bengali-Assamese script, and has historically been used to write Sanskrit within Bengal. It is one of the most widely adopted writing systems in the world . It is one of the official scripts of the Indian Republic. It is used as the official script of the Bengali language in Bangladesh, West Bengal, Tripura, and Barak valley of Assam. It was the sole official script for the Meitei language in Manipur until the passage of the Manipur Official Language (Amendment) Act, 2021.
Old Tamil is the period of the Tamil language spanning from the 3rd century BCE to the seventh century CE. Prior to Old Tamil, the period of Tamil linguistic development is termed as Proto-Tamil. After the Old Tamil period, Tamil becomes Middle Tamil. The earliest records in Old Tamil are inscriptions from between the 3rd and 1st century BCE in caves and on pottery. These inscriptions are written in a variant of the Brahmi script called Tamil-Brahmi. The earliest long text in Old Tamil is the Tolkāppiyam, an early work on Tamil grammar and poetics, whose oldest layers could be as old as the mid-2nd century BCE. Old Tamil preserved many features of Proto-Dravidian, the reconstructed common ancestor of the Dravidian languages, including inventory of consonants, the syllable structure, and various grammatical features.
