Japanese

<p>
	In an earlier lesson we've already learned that in the plain form,
	we can drop <strong>です</strong> after <strong>い-adjectives</strong>,
	and that we can change <strong>です</strong> into <strong>だ</strong> after nouns and <strong>な-adjectives</strong>.
</p>

<p>
	In casual conversation with people we know well,
	we can even drop the <strong>だ</strong> after nouns and <strong>な-adjectives</strong>.
</p>

<table class="ui celled table">
    <tbody>
        <tr data-item="219530"></tr>
		<tr data-item="219533"></tr>
		<tr data-item="219538"></tr>
    </tbody>
</table>

<p>
	In the last sentence above,
	it would be grammatically wrong to use to use <strong>だ</strong> in front of the question particle <strong>か</strong>.
	Though <strong>です</strong> is frequently used in front of the question particle,
	it is mandatory to drop <strong>だ</strong> when using the question particle.
</p>

<p>
	Be careful with using <strong>か</strong> without using the copula <strong>です</strong>,
	because in the wrong situation, it can easily sound excessively harsh or rude.
</p>

<p>
	In casual speech with close friends or people lower in status, it's possible to use the plain form in invitations.
</p>

<table class="ui celled table">
    <tbody>
        <tr data-item="253132"></tr>
		<tr data-item="253134"></tr>
		<tr data-item="253135"></tr>
    </tbody>
</table>

<p>
	As you can see in the last sentence, invitations can be made even more informal by dropping the <strong>か</strong>.
	And while we're at it, why not drop the object particle after <strong>ビール</strong> as well?
</p>

<p>
	In casual speech in general, we can drop the particle <strong>か</strong> in question sentences,
	and instead use a rising intonation at the end of the sentence.

<table class="ui celled table">
    <tbody>
        <tr data-item="219534"></tr>
		<tr data-item="219539"></tr>
