u and uː vowel signs of Malayalam

The reformed or simplified orthographic script style of Malayalam was introduced in 1971 by this government order. This is what is taught in schools. The text book content is also in reformed style. The prevailing academic situation does not facilitate the students to learn the exhaustive and rich orthographic set of Malayalam script. At the same time they observe a lot of wall writings, graffiti, bill-boards and handwriting sticking to the exhaustive orthographic set. [Read More]

മലയാളത്തിലെ ‘ഉ’കാര ചിഹ്നങ്ങൾ

പരിഷ്കരിച്ച മലയാള ലിപിയാണല്ലോ ഇന്നു പാഠപുസ്തകത്തിലുള്ളതും വിദ്യാലയങ്ങളിൽ പഠിപ്പിക്കുന്നതും. അതുകൊണ്ടു തന്നെ ഔപചാരിക വിദ്യാഭ്യാസത്തിൽ മലയാളത്തിന്റെ തനതുലിപിയുടെ ശൈലീഭേദങ്ങൾ പരിചയിക്കുവനുള്ള അവസരം നമുക്കു കിട്ടാറില്ല. പക്ഷേ ചുമരെഴുത്തുകളിലും, ബസ്സിലെ ബോർഡുകളിലും, തനതുമലയാളം എഴുതിശീലിച്ച മുതിർന്നവരുടെ കയ്യെഴുത്തിലുമൊക്കെയായി ഈ ലിപിരൂപങ്ങൾ നമ്മുടെ മുന്നിലുണ്ടു താനും. ലിപിപരിഷ്കരണത്തിന്റെ ഭാഗമായി വേർപെട്ട കൂട്ടക്ഷരങ്ങൾ മിക്കതും തെറ്റുകളൊന്നുമില്ലാതെ നമ്മുടെ കയ്യെഴുത്തുകളിൽ അറിഞ്ഞോ അറിയാതെയോ കൂടിച്ചേരാറുണ്ട്. പക്ഷേ വേർപെട്ട ചിഹ്നങ്ങൾ, പ്രത്യേകിച്ച് ു, ൂ ചിഹ്നങ്ങൾ വ്യഞ്ജനത്തോടു ചേർത്തെഴുതുമ്പോൾ ശൈലികൾ കൂടിക്കുഴഞ്ഞ് പോവുകയും ചെയ്യുന്നു. ചുവടെയുള്ള ചിത്രം നോക്കുക. [][1]ഉ-ചിഹ്നങ്ങളുടെ ഉപയോഗം ചുമരെഴുത്തിൽ. പച്ചയടയാളത്തിനുള്ളിൽ പരിഷ്കരിച്ച ലിപി, നീലയിൽ തനതു ലിപി എന്നിവ കാണാം. [Read More]

Stylistic Alternates for ച്ച, ള്ള in Manjari and Chilanka fonts

The ligatures for the Malayalam conjuncts ച്ച, ള്ള have less popular variants as shown below The second form is not seen in print but often in handwritten Malayalam. I have seen it a lot in bus boards especially at Thiruvananthapuram. There are no digital typefaces with the second style, except the Chilanka font I designed. It uses the second variant of ച്ച. I got lot of appreciation for that style variant, but also recieved request for the first form of ച്ച. [Read More]

Number spellout and generation in Malayalam using Morphology analyser

Writing a number 6493 as six thousand four hundred and ninety three is known as spellout of that number. The most familiar example of this is in cheques.

Towards a Malayalam morphology analyser

Malayalam is a highly inflectional and agglutinative language. This has posed a challenge for all kind of language processing. Algorithmic interpretation of Malayalam’s words and their formation rules continues to be an untackled problem. My own attempts to study and try out some of these characteristics was big failure in the past. Back in 2007, when I tried to develop a spellchecker for Malayalam, the infinite number of words this language can have by combining multiple words together and those words inflected was a big challenge.
