SayJack New Site Design

Dear members,

I have just deployed the latest website design. From now on I can keep you posted about the development of the site and my learning language experience with this blogging feature on the site.  I am only writing in English for now, but if there are more important things I would try to translate them to all JACK languages.

Please feel free to write me comments for any questions or suggestions you have. Thanks!


Essential Concepts and Terms for Grammar Study


A verb is a word to convey an action (e.g. run, read, bring), or a state of being (e.g. is, has, live). We will call them action verbs and non-action verbs respectively.

It is an essential element in a sentence.


A noun is a word to represent an object (e.g. book), a concept (e.g. chemistry) and so forth. A pronoun is a word designated to substitute a noun (e.g. this, he, them). A proper noun is a noun representing a unique entity (e.g. London, John).

Pronouns are relatively few. The rest of the nouns belong to an open category, with new words emerged and added to the dictionary in a living language.


An adjective (e.g. big) is a word designated to modify a noun (e.g. house).

Notice that many nouns (including pronouns) can be used to modify other nouns (e.g. chocolate factory, our country). Some modified forms of verbs can also be used to modify nouns too (e.g. smiling girl, broken heart).


An adverb is a word used to modify adjectives, verbs, another adverbs, and even a whole sentence, but never used to modify nouns.

In English, an adverb often ends in -ly (e.g. happily). Other common example adverbs are: very, more, indeed.


A particle is a word used to indicate relationships between the word it tries to link (its object), and the rest of the sentence.

In English, it is usually called preposition (e.g. in, at, for), because it is used before its object. In Japanese or Korean, it is also called postposition or marker.

Modifying a Word: Conjugation and Declension

Conjugation is modifying a verb from its dictionary or principle form. Declension is the modification for nouns and adjectives.

In English, for example, goes is a modified form of the verb go, and men is a modified form of the noun man.


A phrase is part of a sentence which by itself is meaningful.

The most common types of phrases are noun phrases and verb phrases, which function like nouns and verbs respectively in a sentence.

Subject and Predicate

A complete sentence usually contains a subject and a predicate. A subject is a noun or noun phrase in a sentence, it is what the sentence is about. A predicate describes the subject in a sentence.

Running is a good exercise.
Running is the subject, and is a good exercise is the predicate.

Object and Transitive/Intransitive Verbs

An object which complements an action verb completes the verb’s meaning. It is always part of a predicate.

A direct object answers the question “what?” in a sentence, and an indirect object is usually the recipient of the direct object.

I give you a book.
book is the direct object and you is the indirect object

Not all action verbs take objects. Verbs that take objects are called transitive verbs, those do not take objects are called intransitive verbs. A verb can be both transitive and intransitive in different situations.

She breaks the vase.
break is a transitive verb
He jumps.
jump is an intransitive verb
I eat (apples).
eat is both transitive and intransitive

    Lapinski Cho

    My name is Lapinski (ok… it’s just a nickname, my real name is Lap). You may already know me on facebook if you are a member of my group. I love languages, and I have a strong computer programming background as well. I came up with the idea of bringing the most cutting-edge web technology to the domain of language learning, and that’s why I am building this language learning website for everyone.

  4. Why is it called

    JACK = Japanese, American English, Chinese and Korean.

  5. Do you have terms of use and privacy policy for your website?

    We have it here.

Technical Support

  1. I do not see any Asian characters on the website.

    If you are a Windows XP user, you can follow the instruction to activate East Asian options on your computer here.

    Otherwise, you may need to download and install an Asian font of your choice. It is easy and you can do it yourself.

    You may preview and download Japanese fonts here, Chinese fonts here and Korean fonts here.

    1. For Windows user, make sure you have administrative privilege to install new fonts to your computer.
    2. Go to Control Panel (Click on “Start” button, “Control Panel” can usually be seen under “Settings”), and click on “Fonts” folder (in Control Panel’s classic view).
    3. Choose “Install New Fonts” from the File menu (left upper corner). You will see an “Add Fonts” dialog box. Select the appropriate folder (where your font file is saved), Windows will retrieve the font name that you can install.
    4. Install the font of your choice and restart your browser. You should see Asian characters when you come back to our website!
  2. A dialog box pops up when I run the recorder.

    It is because we need to ask for your permission to run the recorder in your computer. It is a security feature to protect you from third-party eavesdropping.

    You simply need to click on “Run” or “Trust” on the dialog box, and our recorder will be able to gain access to the microphone of your computer. Check the appropriate checkbox to remember this setting, so that you won’t see the dialog box again next time you run the recorder.

  3. I do not see any recorder on the website.

    If you do not see our recorder on your browser, it could be one of the following 2 reasons:

    1. Our recorder requires Java to run. Your computer may not have Java installed, or its version is not compatible to run our recorder. In this case you may see a red mark in the display area. You may want to download the latest version of Java plugin for your browser for free, and try again.
    2. For the first time our recorder gets ready to run, you will see a dialog box asking your permission. You will see this dialog box even if you have blocked popup dialog boxes in your browser settings. You will need to click on “Trust” or “Run” to run our recorder. Otherwise, our recorder will not run.
  4. Some of the Asian characters are too small to be identified.

    Try making the font size bigger. For Firefox, the shortcut keys are pressing “Ctrl” and “+” for getting one size up. To go back to normal font size, press “Ctrl” and “0″.

  5. I do not hear anything when I click on an audio icon.

    Please try to turn on the volume, and make sure your computer can play other audio files first. (Try YouTube and see if you can hear anything from a video.)

    In general, if you could watch a YouTube video with audio, but you could not hear some audio files from our site, it could be due to slow internet connection during some certain time of a day. We have limited audio recording to be at most 6 seconds long, but it could still take up to 10 seconds to load the audio file when the connection is slow. So please wait longer after you click on audio listening icons and see if it helps.
