Two other affixes, infixes and circumfixes, are also attested in some languages.

另外两种词缀，中缀和框缀，在某些语言中也得到证实。

Bound morphemes can be prefixes, suffixes, or infixes.

语素可以是前缀、后缀或中缀。

Do you think the plural morpheme -s in the following examples is an infix?

初步解中缀的概貌之后，我们来尝试一个简单的挑战。你认为句中表示复数的语素-s是中缀吗？

Note that in the above examples, the infix -um- is inserted after the first consonant of the adjectival root.

注意，在上述子中，中缀-um-插入到形容词词根的第一个辅音之后。

But a closer scrutiny shows that it does not count as an infix.

但仔细考察就会发现它们并不能算是中缀。

The morpheme -s in the above two words does look like an infix: after all, it is inserted in a word.

上述两中的语素-s看起来很像中缀：毕竟，它们是插在词的中间。

Unlike prefixes or suffixes that are attached into a word without breaking up other morphemes, infixes are inserted between a morpheme, instead of being placed before or after a morpheme.

与前缀或后缀不同，它们附加到一个词中不会破坏其他语素，中缀是插入到一个语素之间，而不是放在语素之前或之后。

The essence of the property of an infix, as we have shown, is that it does not follow or precede a morpheme, but is inserted in a morpheme.

正如前文所示，中缀最基本的性质是它们不附着在一个语素之后或之前，而是插入到一个语素中间。
