<p>In Old Chinese (from earliest attested times until 漢), all characters had a very complex pronunciation; they had diphthongs or triphthongs, two or three consonants each in the beginning and in end.

<p>becoming:</p>

<p>This is indecipherable, right? To fix the situation, meaningless suffixes were added. "Well you said “鼠” a rat — or did you mean “數” to count, or “屬” to belong to, or “暑” a hot and humid day?"

<p>You can see: </p>

<ul>

<li>Some markers were added not for significant meaning, but for unambiguity. </li>
<li>One-character words became rare and two-character words more common. </li>
</ul>

<p>In the beginning “老” was a marker for reverence, but in “老鼠”, it seemed to have been borrowed to be a marker purely for disambiguity, as you do not normally revere a rat. 
Similarly “子” was a diminutive ending (compare “孩子”, “小子”, also English “-y” as in “Kitty”, or “-et” in “nymphet”), but it was borrowed in “獅子” purely for disambiguity — when you say “獅子” you do not mean it to be cute!</p>

### Answer by username_2 on 2016-11-30. Score: 4

A bit late here, but @Thomas Hsieh, I think, was completely wrong (no offense).

In Old Chinese (from earliest attested times until 漢), all characters had a very complex pronunciation; they had diphthongs or triphthongs, two or three consonants each in the beginning and in end. (See: [複輔音](https://zh.wikipedia.org/wiki/%E5%A4%8D%E8%BE%85%E9%9F%B3))

Throughout Middle Chinese (from 魏晉 on until 元, a loose term though), most consonant clusters had been gradually lost.
I guess this was because the Chinese Empire had expanded considerably and was constantly at war with foreign people. As a result, many 2nd-language learners arose; since they could not speak Old Chinese well, they simplified their pronunciation in a strange manner.

In the end, the native Chinese adopted simplified Chinese as well.
However, many words had no longer been recognizable.

Imagine:

> When in the Course of human events it becomes necessary…

becoming:

> Wa ee da ko oo hoo ma ee va ee bee ko na see sa ree…

This is indecipherable, right? To fix the situation, meaningless suffixes were added. "Well you said “鼠” a rat — or did you mean “數” to count, or “屬” to belong to, or “暑” a hot and humid day?" Hence, we agreed on “老鼠” for mouse, “計算” for to count, “屬於” for to belong to, and “大熱天” for a hot and humid days to remove the ambiguity.

You can see:

* Part of ancient lexicon was obsolete, and remain in use solely in written Chinese, and helped to form the distinction of 文言(written Chinese) and 白話(vernacular Chinese).
* Some markers were added not for significant meaning, but for unambiguity.
* One-character words became rare and two-character words more common.

In the beginning “老” was a marker for reverence, but in “老鼠”, it seemed to have been borrowed to be a marker purely for disambiguity, as you do not normally revere a rat.
Similarly “子” was a diminutive ending (compare “孩子”, “小子”, also English “-y” as in “Kitty”, or “-et” in “nymphet”), but it was borrowed in “獅子” purely for disambiguity — when you say “獅子” you do not mean it to be cute!

I wish to leave comment instead, but I am new user, so...

Some Chinese words @Thomas Hsieh mentioned in answer and comment are wrong.

First, I'm pretty sure 鼠佬 and 虎佬 are not used in Mandarin Chinese, Cantonese, and Written Chinese. I can't get any meaning from them.

Second, 甜頭 does not mean sweetness. It means benefit (好處), the opposite of 苦頭.

To be honest, I never realise 老虎 and 老鼠 have the same prefix. I can't think of any reason why 老虎 and 老鼠 have 老 as prefix.
