Morpheme boundary

The boundary between the prefix and verb is mostly unclear to English speakers unfamiliar with linguistics and Latin. For example, for a long time, "descend" (de- + scend) was thought to be made of des- and cend, hence it was also spelled dis- and dys-.

Spelling

Due to assimilation, the roots of some of the English verbs listed here are difficult to recognize. For example, ad- + ludo ("play") results in allude rather than *adlude. On the other hand, once a learner knows the rule they are less likely to make spelling mistakes: That the word aggressive is spelt with gg is due to the fact that it derives from ad + gredior, with -dg-, as it is more difficult to pronounce, having been turned into the easier -gg- (so that *agressive must be considered wrong).
