ad-词源中文解释
这个词缀表示方向或附加，源自拉丁语 ad，意为“到，朝向”（空间或时间）； 作为前缀时，有时仅仅是强调作用，表示“关于，与...有关”，源自 PIE 词根 *ad-，意为“到，靠近，于...之间”。
在 sc- 、sp- 和 st- 之前，简化为 a-； 在许多辅音前改为 ac-，然后根据后面的辅音重新拼写为 af- 、ag- 、al- 等（如 affection 、aggression）。还可以参考 ap-（1）。
在古法语中，所有情况下都缩写为 a-（这种演变在梅洛文吉安拉丁语中已经开始），但法语在14世纪重新塑造了其书写形式，效仿拉丁模式，英语在15世纪也从古法语中学习了这种方式。在许多情况下，发音也随之改变。
在中世纪末期，法语和英语的过度纠正“恢复”了一些从未有过的单词的 -d- 或重复辅音（如 accursed 、afford）。在英格兰，这个过程比在法国更进一步（在法国，方言有时会抵制这种学究式的语言），导致了英语中的 adjourn 、advance 、address 、advertisement（现代法语为 ajourner 、avancer 、adresser 、avertissement）。在现代的词汇构成中，有时认为 ad- 和 ab- 是相反的，但这在古典拉丁语中并不是这样。
