for vs of
Look the topic of this note. "Phonetic Symbols for English" Why is the word "for" instead of "of"?
=> That's a great question! It's exactly the kind of question that helps you develop an English "feel."
The short answer is:
- phonetic symbols for English ✅ (the natural expression)
- phonetic symbols of English ❌ (not the usual expression)
The reason is the meaning of the prepositions.
"for" = used for (for=用于、适用对象)
When we say:
phonetic symbols for English
we mean:
phonetic symbols used for representing表示记录（代表、象征，这是原意） English pronunciation.
Here, for means "used for"(用于...) or "intended for."(供...使用)
Similar examples:
- glasses for reading 看书用的眼镜
- medicine for children 儿童用药
- a dictionary for learners 供学习者的字典
- a textbook for beginners 供初学者的教材
So:
phonetic symbols for English
means
a set of phonetic symbols used for English.
There are some other meanings of "for":
Purpose
This tool is for cutting wood.
这个工具是用来切木头的。
Receiver
This gift is for you.
这个礼物是给你的。
Time period
I lived there for five years.
我在那里住了五年。
Reason
Thank you for your help.
谢谢你的帮助。
"of" = belonging to / part of(of=属于、所属)
of usually expresses a relationship like possession(拥有), composition(组成), or belonging(属于).
For example:
- the capital of France
- the history of China
- the pronunciation of English ✅
Notice the difference:
- the pronunciation of English = the way English is pronounced.
- phonetic symbols for English = symbols used to write English pronunciation.
Compare these
✅ a dictionary for English learners
- a dictionary intended for English learners
❌ a dictionary of English learners
- this would mean a dictionary about English learners, which is a completely different meaning.
Another pair:
- a keyboard for Mac ✅ (a keyboard used with a Mac)
- the keyboard of my Mac ✅ (the keyboard that belongs to my Mac)
One more thing
If you're talking about the International Phonetic Alphabet (IPA), people also often say:
the IPA symbols for English
or
the English IPA symbols
Both are natural.
So your intuition was good to ask about for vs of. This distinction appears everywhere in English, and once you start noticing it, you'll understand many noun phrases much more naturally.
