lower-case letters

基本解釋

This behavior applies also to out-of-vocabulary words if you type them in lower-case letters into your dictionary, such as ipod.
這一行為也適用于詞匯表以外的單詞，如果將它們以小寫(xiě)字母的形式輸入到字典中的話(huà)，例如 ipod。
Note: To make sure, that you can find all occurrences of the specified terms, and because these terms are not known by the underlying dictionary, write the terms in all lower-case letters.
注意：要確定您可以找到指定術(shù)語(yǔ)的所有匹配項(xiàng)，并且由于這些術(shù)語(yǔ)對(duì)于底層字典是未知的，需要全部使用小寫(xiě)字母寫(xiě)入術(shù)語(yǔ)。
All names are lower-case letters, there are no more than 10 people in a group, and no name is more than 12 characters in length.
所有名字都是小字字母，每個(gè)圈子不會(huì)超過(guò)10個(gè)人，所有名字都小于或等于12個(gè)字符長(zhǎng)度。

They would just be letters—and lower-case ones, to boot.
