To answer your question, here's a breakdown of what might be considered "against" when using prefixes:
1. Misusing Prefixes:
* Incorrect meaning: Using a prefix that doesn't accurately reflect the intended meaning. For example, using "un-" to mean "not" when it should mean "opposite" (e.g., "unhappy" is correct, but "unfriend" isn't).
* Inconsistent usage: Applying a prefix to a word that doesn't typically take that prefix (e.g., "un-delicious").
* Creating redundant words: Using a prefix that already exists within the word (e.g., "re-start" when "start" already implies a restart).
2. Awkward or Uncommon Prefixes:
* Overly obscure prefixes: While there are many prefixes, some are rarely used or have very specific meanings. It's best to stick with common prefixes for clarity.
* Prefixes that clash with the base word: Sometimes, a prefix creates an awkward combination with the base word (e.g., "pre-wisdom").
3. Contextual Considerations:
* Formal vs. informal: Some prefixes might be more suited for formal writing than informal speech.
* Specificity: Depending on the context, a more specific prefix might be needed to convey the intended meaning.
Key takeaway:
There aren't hard-and-fast rules against using prefixes. The main goal is to use them correctly and effectively to communicate your meaning clearly and accurately. If you're unsure about a particular prefix or word combination, consult a dictionary or style guide.
