1. linking two nouns to show that the first one belongs to, is part of, or is assoc
linking two nouns to show that the first one belongs to, is part of, or is associated with the second — typically a person, place, or organisation that owns or holds it, as in the friends of Maya, the streets of Taipei, or the windows of the old house.

[thing] + of + [named person] for possession

- 's (possessive)
preferred for people: 'Maya's bag', not 'the bag of Maya'.
- belonging to
more formal and longer; usually used for emphasis.
文法句型
[noun] + of + [person/place/group]
用法筆記
Subject is usually a thing, role, or part; the noun after 'of' names the owner, place, or group it belongs to. With people, the possessive 's (Anne's diary) is more common in everyday speech than 'of'.

2. placed after a measurement word, a number, or a quantifier to mark the substance
placed after a measurement word, a number, or a quantifier to mark the substance or set being measured, counted, or partitioned — answering 'how much' or 'how many' rather than 'whose' or 'what is inside'. Common with units like kilo, litre, cup, and with quantifiers like some, most, half, none.
Carlos drank a tall glass of orange juice with his breakfast.
[unit/container] + of + [substance]
Maya bought three kilos of apples at the market on Saturday.
[number + unit] + of + [countable plural]
Most of the students walked home together after the late class.

The waiter brought a small plate of warm bread to the table.
文法句型
[number/amount/unit] + of + [noun]
some/many/most/few + of + [noun phrase]
用法筆記
Use 'of the' (not bare 'of') with words like some, many, most, few, all, each, none when the noun has 'the', 'my', 'these', etc. — 'most of the cake', not 'most of cake'. Bare 'most cake' is fine for general statements.

3. after a word naming a container, vessel, or organised group, to identify the spe
after a word naming a container, vessel, or organised group, to identify the specific contents or members inside — describing the kind of stuff that fills it, not how much there is. Examples: a box of toys (toys are inside), a basket of flowers, a team of doctors.

container + of + contents

[item] + of + [content theme]

- containing
more formal and explicit; 'a jar containing honey' vs 'a jar of honey'.
- full of
stresses that something is completely filled.
文法句型
[container/group noun] + of + [contents]
用法筆記
Distinguish from sense 2 (AMOUNT): sense 3 emphasises what fills the container or group ('a box of toys' = box has toys inside); sense 2 measures quantity ('two boxes of toys' = counting). The line is fuzzy and contexts often allow either reading.

4. joining a direction word — such as north, south, left, right, or top — to a fixe
joining a direction word — such as north, south, left, right, or top — to a fixed point, so the listener knows where one place sits compared with another.

Common fixed phrases: 'on top of', 'in front of', 'at the back of', 'to the left/right of', 'north/south/east/west of'. The 'of' is required and cannot be dropped.

5. marking a behaviour, quality, or feature as something you usually expect from a
marking a behaviour, quality, or feature as something you usually expect from a particular person, group, or thing — used after words like 'typical' or 'characteristic' to point to the source of that pattern.

typical of + [person] for usual behaviour

typical of + [group/place]

- characteristic of
more formal; emphasises a defining quality.
- unlike
'that's unlike Marcus' = not his usual behaviour.
文法句型
[quality/feature/behaviour] + typical/characteristic + of + [person/group/thing]
that's (so) typical + of + [person/group]
用法筆記
Restricted to 'typical of', 'characteristic of', and a few similar words ('representative of', 'symptomatic of'). Subject names a feature, action, or quality; the noun after 'of' names whose pattern it fits. Distinguish from sense 9, which uses the 'it + be + [adj] + of + [person] + to-infinitive' frame to judge a single action.

文法句型
noun + of + material noun
用法筆記
Subject noun is normally a concrete object; the noun after 'of' names the raw stuff. Often appears in the fixed pattern 'made of [material]', which keeps the material visible in the final product (compare 'made from', where the original material is changed).

8. required after a fixed list of adjectives (afraid, fond, proud, tired) and verbs
required after a fixed list of adjectives (afraid, fond, proud, tired) and verbs (think, dream, speak, remind, accuse) to introduce the object of the feeling, mental act, or speech — the partner word demands 'of' as its only correct preposition.

verb + of: speak of [topic]
Marcus was tired of waiting at the bus stop in the rain.

用法筆記
These pairings are fixed by the verb or adjective and must be learned one by one. Common adjectives: afraid of, proud of, fond of, tired of, aware of, jealous of. Common verbs: think of, dream of, speak of, remind of, accuse of, approve of. Subject noun is usually a person or animate being.

文法句型
it + be + adjective + of + person + to-infinitive
用法筆記
Distinguish from sense 8: this sense judges the person's action ('It was kind of you to help' = you were kind because you helped). Compare 'It is important for you to help' — 'for' rates the situation, not the person. Common adjectives in this slot: kind, nice, good, sweet, generous, rude, mean, stupid, silly, brave, foolish, careless.

formal, mostly written; for documents and reports.
文法句型
noun + of + topic noun
用法筆記
Pairs naturally with information-bearing nouns: account, story, picture, photo, map, list, review, description, study, knowledge, idea. Often interchangeable with 'about' after these nouns, but 'of' sounds slightly more formal and tighter ('a story of love' vs 'a story about love').

The first noun is a category word (city, village, island, month, day, name, title, role, job, idea, problem); the noun after 'of' is the specific identity. Distinguish from sense 7 (MADE OF) by checking if the noun after 'of' names a thing (use this sense) or a material (use sense 7).

文法句型
action noun + of + receiver noun

The first noun is normally a deverbal noun (repair, murder, teaching, painting, building, destruction, treatment, examination); the noun after 'of' is what would be the direct object of the related verb. Compare with sense 1 (POSSESSION): 'the painting of Carlos' = a painting that shows Carlos (sense 12 reading) or a painting that Carlos owns (sense 1 reading) — context decides.
