Turkic languages

Note that some Turkic languages like Azeri and Turkmen use a similar Latin alphabet (often Jaŋalif) and similar words, and might be confused with Turkish. Azeri has the letters Əə, Xx and Qq not present in the Turkish alphabet, and Türkmen has Ää, Žž, Ňň, Ýý and Ww. Latin Characters uniquely (or nearly uniquely) used for Turkic languages: Əə, Ŋŋ, Ɵɵ, Ьь, Ƣƣ, Ğğ, İ, and ı. All Turkic languages can form long words by adding multiple suffixes.

Turkish (Türkçe/Türkiye_Türkçesi)

Turkish Alphabet

Lowercase: a b c ç d e f g ğ h ı i j k l m n o ö p r s ş t u ü v y z

Uppercase: A B C Ç D E F G Ğ H I İ J K L M N O Ö P R S Ş T U Ü V Y Z

Common words

• bir — one, a
• bu — this
• ancak — but
• oldu — was (happened)
• şu — that

Misc.

• The letter "j" is only used in loanwords.
• Words never begin with "ğ"
• Look for common word endings. Tense changes in Turkish verbs are created by adding suffixes to the end of the verb. Pluralizations occur by adding -lar and -ler.
  • Common Tense Changes: -yor -mış -muş -sun
  • Possessivity/person: -im -un -ın -in -iz -dur -tır
  • Example: Yaptı , "[He] did it"; Yap is the verb stem meaning "to do", -mış indicates the perfect tense, -tır indicates the third person (he/she/it).
  • Example: Adalar, "Islands"; Ada is a noun meaning "island", -lar makes it plural.)
  • Example: Evimiz, "Our house"; Ev is a noun meaning "house", -im indicates the first-person possessor, which -iz then makes plural.)

Azeri (Azərbaycanca)

Azeri can be easily recognized by the frequent use of ə. This letter is not used in any other officially recognized modern Latin alphabet. In addition, it uses the letters x and q, which are not used in Turkish.

• Common words: və, ki, ilə, bu, o, isə, görə, da, də
• Frequent use of diacritics: ç, ğ, ı, İ, ö, ş, ü
• Words ending in -lar, -lər, -ın, -in, -da, -də, -dan, -dən
• Words never beginning with ğ or ı
• Words rarely beginning with two or more consonants
• Transliteration of foreign words and names, e.g. Audrey Hepburn = Odri Hepbern

Chinese (中文)

• No spaces, except between punctuation marks and (sometimes) foreign words.
• Arabic numerals (0-9) sometimes used
• Punctuation:
  • Period 。(not .)
  • Serial comma 、(distinguished from the regular comma ，)
  • Ellipse …… (six dots)
• No hiragana, katakana, or hangul
• May be written vertically

Simplified Chinese (简体) vs Traditional Chinese (繁體)

Note: Many characters were not simplified. As a result, it is common for a short word or phrase to be identical between Simplified and Traditional, but it is rare for an entire sentence to be identical as well.

Common radicals different between Traditional and Simplified:

• Simplified: 讠钅饣纟门(e.g. 语 银 饭 纪 问)
• Traditional: 訁釒飠糹門(e.g. 語 銀 飯 紀 問)

Common characters different between Traditional and Simplified:

• Simplified: 国 会 这 来 对 开 关 门 时 个 书 长 万 边 东 车 爱 儿
• Traditional: 國 會 這 來 對 開 關 門 時 個 書 長 萬 邊 東 車 愛 兒

Standard written Chinese (based on Mandarin) vs written Vernacular Cantonese

See also: zh:粵語

Note: Apart from Hong Kong, there are also Cantonese-speakers in southern Mainland China, Malaysia and Singapore, so written Cantonese can be written in either Simplified or Traditional characters.

Common characters in Vernacular Cantonese that do not occur or seldom occur in Mandarin:

• 嘅 咗 咁 嚟 啲 唔 佢 乜 嘢 嗰 冇 睇

Some of the above characters are not supported in all character encodings, so sometimes the 口 radical on the left is substituted with a 0 or o, e.g.

• o既 0既

Sometimes, different Chinese characters are used to express the same meaning in Cantonese and Mandarin. If you use the one commonly used in Cantonese to express the same meaning when you are speaking or writing Mandarin, a native speaker may be confused or even find it difficult to understand, and vice versa. Some examples are: (Cantonese vs Mandarin)

• 食vs吃(eat) 飲vs喝(drink) 企vs站(stand) 凍vs冷(cold) 落vs下(down) 著vs穿(wear) 讀vs唸(read) 鬧vs罵(scold) 計vs算(calculate) 咪vs別(do not) 行vs走(walk/go) 先vs才(then)

There are Chinese words used to construct vocabularies used in Cantonese that are not or seldomly implemented in modern Mandarin. Some examples are: (Cantonese vs Mandarin)

• 成日vs整天(always) 傾計vs聊天(talk) 返工vs上班(go to work) 溫書vs溫習(study) 影片vs視頻(video) 隔離vs旁邊(nearby) 起屋vs蓋樓(build a house) 聽日vs明天(tomorrow) 巴閉vs囂張(arrogant) 搞掂vs完成(finished) 定係vs還是(or) 靚仔vs帥哥(handsome male) 鍾意vs喜歡(like) 犀利vs厲害(powerful) 同埋vs和/及(and) 黐綫vs瘋的(crazy) 雪櫃vs冰箱(fridge)

Cantonese vocabularies constructed by Cantonese words are used in daily life in southern China and are not used in modern Mandarin. Some examples are:

• 咪咁(don't be like this) 好冇(ok?) 玩嘢(to play tricks) 做嘢(to work) 睇戲(to watch a film/movie) 唔知(don't know) 埋嚟(come) 嗰個(that) 咁嘅嘢(such thing) 佢哋(they) 咩事/乜事(what?) 冇嘢(nothing) 嗰陣(at that moment) 越嚟越多(more and more) 我嘅(mine) 梗係(of course) 𥄫(to peek) 冧佢(love him/her) 拎畀我(take it to me) 嘥曬(everything is wasted) 你啱(you are right) 𢫏住(to cover something) 冚唪唥(all) 撳實(to press something tightly) 瞓覺(to sleep) 掟石仔(to throw a tiny stone) 唓[a modal word to express comtemption] 噃[a modal word for reminding or warning someone] 詏交(to argue) 好嬲(very angry) 心悒(feeling depressed in heart) 𧨾女仔(to please a girl) 得咁多咋(only this much) 做好咗(done something well)

Finally, when terms are introduced from other countries(especially the US and the UK) to China, Cantonese and Mandarin often get different translations, where Cantonese often translates according to pronunciation of the terms in English and Mandarin often translates according to the meaning of the terms. Some examples are: (Cantonese vs Mandarin)

• 的士(dik1 si2, has no direct meaning, translated according to the English pronunciation.) vs 出租車(chū zū chē, meaning cars for renting.), translated from Taxi.
• 巴士(baa1 si2, has no direct meaning, translated according to the English pronunciation.) vs 公車(gōng chē, meaning public cars.), translated from Bus.
• 多士(do1 si2, has no direct meaning, translated according to the English pronunciation.) vs 土司(tǔ sī, has no direct meaning, translated according to the English pronunciation.), translated from Toast.
• 騷(sou1, has no direct meaning, translated according to the English pronunciation.) vs 秀(xìu, has no direct meaning, translated according to the English pronunciation), translated from Show.
• 士多(si2 do1, has no direct meaning, translated according to the English pronunciation) vs 小店(xiǎo diàn, meaning small shop), translated from Store.
• 𨋢(lip1, has no direct meaning, translated according to the English pronunciation) vs 升降機(shēng jiàng jī, meaning machine that elevates and lowers itself), translated from Lift/Elevator.

• Western-style punctuation marks
• Western-style spacing
• Hangul letters(phonetic) ex: ㅂ(b in book) ㅈ(j in jump) ㅅ(s in sock)ㅊ(ch in champion) ㅍ(p in pox)

• Circles and ellipses are commonplace in Hangul; are exceedingly rare in Chinese.
• General appearance has relatively-uniform complexity, as contrasted with Chinese or Japanese.

Bengali

The Bengali alphabet or Bangla alphabet (Bengali: বাংলা বর্ণমালা, bangla bôrnômala) or Bengali script (Bengali: বাংলা লিপি, bangla lipi) is the writing system, originating in the Indian subcontinent, for the Bengali language and is the fifth most widely used writing system in the world. The script is used for other languages like Assamese, Maithili, Meithei and Bishnupriya Manipuri, and has historically been used to write Sanskrit within Bengal.

Bengali

Bengali has unique 50 letter Alphabet.

• The Bengali script has a total of 9 vowel graphemes, each of which is called a স্বরবর্ণ swôrôbôrnô "vowel letter". The swôrôbôrnôs represent six of the seven main vowel sounds of Bengali, along with two vowel diphthongs. All of them are used in both Bengali and Assamese languages.

অ আ ই ঈ উ ঊ ঋ এ ঐ ও ঔ

• The Bengali script has a total of 39 Consonants. Consonant letters are called ব্যঞ্জনবর্ণ bænjônbôrnô "consonant letter" in Bengali. The names of the letters are typically just the consonant sound plus the inherent vowel অ ô. Since the inherent vowel is assumed and not written, most letters' names look identical to the letter itself (the name of the letter ঘ is itself ghô, not gh).

ক খ গ ঘ ঙ চ ছ জ ঝ ঞ ট ঠ ড ঢ ণ ত থ দ ধ ন প ফ ব ভ ম য র ল শ ষ স হ ড় ঢ় য় ৎ ঃ ং ঁ

Canadian Aboriginal syllabics

In modern writing, Canadian Aboriginal syllabics are indicative of Cree languages, Inuktitut, or Ojibwe, though the latter two are also written in alternative scripts. The basic glyph set is ᐁ ᐱ ᑌ ᑫ ᒉ ᒣ ᓀ ᓭ ᔦ, each of which may appear in any of four orientations, boldfaced, superscripted, and with diacritics including ᑊ ᐟ ᐠ ᐨ ᒼ ᐣ ᐢ ᐧ ᐤ ᐦ ᕽ ᓫ ᕑ. This abugida has also been used for Blackfoot.

Klingon (tlhIngan Hol)

• When written in the Latin alphabet Klingon has the unusual property of a distinction in case; q and Q are different letters, and other letters are either always (e.g. D, I, S) or never (e.g. ch, tlh, v) written in upper case. This causes a large number of words that look quite strange to people who aren't used to it, for example: yIDoghQo', tlhIngan Hol (with mixed case).
• The apostrophe is fairly frequent, especially at the end of a word or syllable.
• Common suffixes: -be', -'a'
• Common words: 'oH, Qapla'
• May use one or more apostrophes in the middle of a word: SuvwI″a'

• common words lo, mi, cu, la, nu, do, na, se;
• paragraphs delimited with ni'o and sentences delimited with .i (or i);
• many five-letter words in consonant-vowel shape CCVCV or CVCCV;
• many short words with apostrophes between vowels, like ko'a pi'o etc.;
• usually no punctuation except for dots;
• may use commas in the middle of words (typically proper nouns).

Toki Pona (toki pona)

• alphabet is all lowercase except loanwords
• no diacritics
• only uses unvoiced consonants in writing, e.g. p, t, k
