This answer is explained better than the one by @Milla. However, without references or another authority to back it up, it sits in the #2 ranking. If you could provide authoritative backing then I think this answer would surpass Milla's, especially since there doesn't appear to be a clear answer for this yet.

"You wouldn't find it (常常) in legal documents and such." This is not the point. The reason you won't find 常常 in legal docs is NOT because the word is informal, but because the word is not **precise**.

So, going by your example sentences, it seems that 通常 is used for statements that happen frequently, both past, present, and future. But, is it ok to use 经常 in your sample sentence, like "事情经常是这样的“. If it is ok, do these two statements imply any difference in the frequency of an event?

<p>通常 means "usually", or "for most of the times". It is used to describe things that would probably happen when certain circumstances are met. But the thing it describe doesn't necessarily happen in a high frequency.</p>

<p>常常 and 经常 could both describe things that </p>

<ol>
<li><p>has a high possibility to happen when certain circumstances are met. The possibility may be higher than expected or average, but isn't necessarily so high as to be called "for most of the time".</p></li>
<li><p>happens in a high frequency.</p></li>
</ol>

<p>But the choice is sometimes a matter of grammar. (I'll explain this later in the examples.)</p>

<p><strong>Note</strong> Since "通常" is for "most of the time", it is often used with "但是(but)" to show that there are exceptions.</p>

<p>example:</p>

<p>我 [经常, 常常] 锻炼身体。</p>

<p>“通常”这个词 [常常, 经常] 和“但是”一起使用。</p>

<p>我锻炼身体之后，[通常] 会去洗个澡。 </p>

<hr>

<p>洗澡水 [经常, 常常] 过热。 （过热 means overheating, so it is one word.）</p>

<p>洗澡水 [常常] 太热，让我很不舒服。 (太热 are two words, 太 (too) 热(hot) )</p>

<p>洗澡水 [常常] 不是太冷，就是太热。 （不是太冷，就是太热 is a long phrase）</p>

<p>The pronunciation of 经常 (jīngcháng) has a stronger stress than 常常 (chángcháng).</p>

<p>So when people use 常常, the stress is more often in the phrase that follows it, while when using 经常, the stress is more often put on the syllable “经” rather than on the others.</p>

<p>So 经常 are usually followed by a word (or a idiom that counts as a verb).
While 常常 could be followed by longer ones like a phrase or a clause, because the stress is not yet used.</p>

<p>But in some informal contexts, people don't care the difference very much.</p>

常常 simply means "often", and is not very formal. You wouldn't find it in legal documents and such.

经常 means "frequently" or "regularly". It's not just conveying the frequency of something, but also its *regularity*.

通常 also conveys frequency, but it's a bit more like "usually". Under such-and-such a condition, *then* something often or usually happens.

If I say 我常常在麦当劳吃饭, it just means that I "often" eat at McDonalds. But if it's 我通常在麦当劳吃饭, then when I have a meal, the "normal" or expected case is that I will be eating at McDonalds.

The difference is not really about the degree of frequency/infrequency.

通常 means "usually", or "for most of the times". It is used to describe things that would probably happen when certain circumstances are met. But the thing it describe doesn't necessarily happen in a high frequency.

常常 and 经常 could both describe things that

1. has a high possibility to happen when certain circumstances are met. The possibility may be higher than expected or average, but isn't necessarily so high as to be called "for most of the time".
2. happens in a high frequency.

But the choice is sometimes a matter of grammar. (I'll explain this later in the examples.)

**Note** Since "通常" is for "most of the time", it is often used with "但是(but)" to show that there are exceptions.

example:

我 [经常, 常常] 锻炼身体。

“通常”这个词 [常常, 经常] 和“但是”一起使用。

我锻炼身体之后，[通常] 会去洗个澡。

---

洗澡水 [经常, 常常] 过热。 （过热 means overheating, so it is one word.）

洗澡水 [常常] 太热，让我很不舒服。 (太热 are two words, 太 (too) 热(hot) )

洗澡水 [常常] 不是太冷，就是太热。 （不是太冷，就是太热 is a long phrase）

The pronunciation of 经常 (jīngcháng) has a stronger stress than 常常 (chángcháng).

So when people use 常常, the stress is more often in the phrase that follows it, while when using 经常, the stress is more often put on the syllable “经” rather than on the others.

So 经常 are usually followed by a word (or a idiom that counts as a verb).
While 常常 could be followed by longer ones like a phrase or a clause, because the stress is not yet used.

But in some informal contexts, people don't care the difference very much.
