<p>夂 is normally used at the top (for example 条條修脩务務夐) or the left (for example 处) of a character, and 夊 at the bottom (for example 愛夏复) or the right (for example 致, see <a href="http://zhongwen.com/d/173/d80.htm">http://zhongwen.com/d/173/d80.htm</a>).</p>

As I know, the 攵, also (informally) known as the 反文, is usually written as a right component, which is actually different from both 夂, the 折文, and 夊, as a bottom component.

<li>「夂」is defined as <em>arriving from behind</em>, but this was probably made up. Apart from the single <em>Shuowen</em> definition, which all other dictionary definitions seem to stem from, there are no recorded words/expressions/phrases which contain「夂」meaning <em>arriving from behind</em>.</li>

<h1>Long Answer</h1>

<p><strong>Is there a difference between 夂 and 夊?</strong></p>

<p>The question is complicated through differing ways of writing these components throughout history, to this very day, often due to confusion as to what「夂」and「夊」actually <em>are</em>. In any given character, different fonts or language standards may use one or the other, or even use the unrelated「攵」.</p>

<blockquote>
  <p>「攵」is completely unrelated to「夂」and「夊」. For reference,「攵」originally depicted a hand「又」holding a beating implement (stick, whip, staff).「攵」, or its variant「攴」, is heavily used as a semantic component to do with <em>disciplining</em>, <em>attacking</em>, or more generally <em>motion</em>.</p>

<p>Here's where things get tricky.</p>

<ol>
<li><p>「夊」did not originally represent a word; it was not an individual character (being found exclusively as part of other characters), nor appear to have any pronunciation, until the <a href="https://en.wikipedia.org/wiki/Qin_dynasty" rel="nofollow noreferrer">Qin</a>-<a href="https://en.wikipedia.org/wiki/Han_dynasty" rel="nofollow noreferrer">Han</a> era. The pronunciation recorded in dictionaries, <strong>楚危切</strong> (Mandarin <strong>suī</strong>), was a word meaning something like <em>slow strides</em>, variously represented as「綏」or「奞」. For all intents and purposes, as part of other characters, it is just a variant form of「止」.</p></li>
<li><p>The <em>shape of</em> (not the <em>word represented by</em>)「夂」is just a variant way of writing「夊」. Note that the stroke「㇏」is just for drawing the big toe and the outline of one side of the foot without the other toes.</p>

<p><a href="https://i.sstatic.net/gxCWm.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/gxCWm.png" alt="enter image description here"></a></p>

<p>The difference in the shapes is trivially just whether the stroke「㇏」protrudes or not, and both shapes are seen, for example in「各」:</p>

<h1><kbd>商<br>甲<br><a href="https://i.sstatic.net/0xsqZ.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/0xsqZ.png" alt="enter image description here"></a><br><a href="http://xiaoxue.iis.sinica.edu.tw/yanbian/Reference/JiaguwenReference" rel="nofollow noreferrer">前</a>5.24.4<br><a href="http://www.guoxuedashi.com/jgwhj/?bhfl=1&amp;bh=22001&amp;jgwfl=" rel="nofollow noreferrer">合集22001</a></kbd><kbd>商<br>甲<br><a href="https://i.sstatic.net/Up1j3.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/Up1j3.png" alt="enter image description here"></a><br><a href="http://xiaoxue.iis.sinica.edu.tw/yanbian/Reference/JiaguwenReference" rel="nofollow noreferrer">甲</a>2589<br><a href="http://www.guoxuedashi.com/jgwhj/?bhfl=1&amp;bh=27625&amp;jgwfl=" rel="nofollow noreferrer">合集27625</a></kbd></h1>

<p>This indicates that「夂」and「夊」are just variant ways of writing <em>upside-down</em>「止」. There was no such rule saying that the stroke must protrude when the component is on the bottom of the character and must not protrude when it's on the top; this is a convention made up later, possibly out of confusion about what「夂」and「夊」actually are, or possibly for aesthetics.</p>

The shapes「夂」and「夊」are writing variants. As a component of a character, the majority of the time it is just a「止」(picture of a foot) pointing in the opposite direction to「止」.

The dictionary definitions are tangential to the component meaning.

* 「夊」is defined as *walking slowly*, an extended meaning from「止」, which represents *motion* in general.
* 「夂」is defined as *arriving from behind*, but this was probably made up. Apart from the single *Shuowen* definition, which all other dictionary definitions seem to stem from, there are no recorded words/expressions/phrases which contain「夂」meaning *arriving from behind*.

「夊」was originally「止」(*a foot*), but pointing in the other direction:

# `商 甲 enter image description here 前8.4.2 合集21837` `篆 enter image description here 說文解字``現代 楷 enter image description here`

Compare「止」:

# `商 甲 enter image description here 甲1532 合集27434`

Here's where things get tricky.

1. 「夊」did not originally represent a word; it was not an individual character (being found exclusively as part of other characters), nor appear to have any pronunciation, until the [Qin](https://en.wikipedia.org/wiki/Qin_dynasty)-[Han](https://en.wikipedia.org/wiki/Han_dynasty) era. The pronunciation recorded in dictionaries, **楚危切** (Mandarin **suī**), was a word meaning something like *slow strides*, variously represented as「綏」or「奞」. For all intents and purposes, as part of other characters, it is just a variant form of「止」.
2. The *shape of* (not the *word represented by*)「夂」is just a variant way of writing「夊」. Note that the stroke「㇏」is just for drawing the big toe and the outline of one side of the foot without the other toes.

   [![enter image description here](https://i.sstatic.net/gxCWm.png)](https://i.sstatic.net/gxCWm.png)

   The difference in the shapes is trivially just whether the stroke「㇏」protrudes or not, and both shapes are seen, for example in「各」:

   # `商 甲 enter image description here 前5.24.4 合集22001``商 甲 enter image description here 甲2589 合集27625`

   This indicates that「夂」and「夊」are just variant ways of writing *upside-down*「止」. There was no such rule saying that the stroke must protrude when the component is on the bottom of the character and must not protrude when it's on the top; this is a convention made up later, possibly out of confusion about what「夂」and「夊」actually are, or possibly for aesthetics.

   # `西周 金 enter image description here 作冊夨令簋 集成4300`

   *Despite their modern appearances, characters which contain*「夊」*on the bottom, such as*「後」*, have no requirement that the stroke must protrude.*
3. *Shuowen* confusingly lists a separate character with an identical shape to「夂」, and gave it a definition 从後至也 (*approaching from behind*) and pronunciation **陟侈切** (**zhǐ**). This definition was probably made-up, and is suggested to be a Simplified form of「致」(from where its definition and pronunciation was derived). For reference,「致」was originally comprised of「至」(both a semantic and phonetic component) and「人」(a semantic component); later on,「夊」was added and「人」was removed.

   # `西周 金 enter image description here 曶鼎 集成2838``秦 簡 enter image description here 睡ㆍ雜35` `篆 enter image description here 說文解字``現代 楷 enter image description here`

   It is surmised that scholars didn't know what「夂/夊」was doing in this character, having not known that「人」was omitted previously, so forced a *Shuowen* definition into existence in an attempt to explain its presence in「致」.
4. *Shuowen* also mentions「夂」in its entry for「冬」:

   > 四時盡也。从仌从夂。**夂，古文終字。**

   This corresponds to some dictionaries listing the pronunciation **zhōng**. This component has an entirely different history, originally depicting objects hanging off the end of a connector, indicating the meaning *end*.

The difference between the two in writing should be clear from these drawings: <http://en.wikipedia.org/wiki/Radical_35> and <http://en.wikipedia.org/wiki/Radical_34> and the stroke animations from <http://en.wiktionary.org/wiki/%E5%A4%8A>
and <http://en.wiktionary.org/wiki/%E5%A4%82>

夂 is normally used at the top (for example 条條修脩务務夐) or the left (for example 处) of a character, and 夊 at the bottom (for example 愛夏复) or the right (for example 致, see <http://zhongwen.com/d/173/d80.htm>).

Originally both characters were quite different (see <http://en.wiktionary.org/wiki/%E5%A4%8A>
and <http://en.wiktionary.org/wiki/%E5%A4%82>), but nowadays there are typically both written as 夂 by most people and most fonts don't make the distinction anymore.

> **Comments:**
> **username_2**: As I know, the 攵, also (informally) known as the 反文, is usually written as a right component, which is actually different from both 夂, the 折文, and 夊, as a bottom component.

Indeed <https://xuehanyu.wikispaces.com/Radicals> mentions that "夊 (...) no modern characters; this radical is often omitted"

> **Comments:**
> **username_4**: That website is referring to '夊' which is a slight variant of '夂'
