Part and whole
What is it a part or member of?
المعنى
A part can be linked to the larger thing, group, or amount it belongs to. This lets us name a piece of an object, a group member, or a share of something. Languages use linking words, endings, or word order, and some have no special form just for this relation. Possession can use the same forms, but Part and whole describes membership or a piece of something rather than ownership.
طريقة التعرّف عليه
Look for something presented as a piece, member, or portion of a larger thing, group, or amount.
في اللغة الأم
Arabic commonly expresses a part and its whole with an iḍāfa, the same noun-linking pattern used for possession. The part comes first without an article, and the whole follows. For one member or a portion taken from a group, Arabic often uses مِن, meaning 'from' or 'of.'
بابُ الثلاجةِ مفتوحٌ. (Bābu al-thallājati maftūḥ.)
The part comes before the whole in an iḍāfa.
واحدٌ من أصدقائي يسكنُ في عمّانَ. (Wāḥidun min aṣdiqāʾī yaskunu fī ʿAmmān.)
مِن introduces the group from which one member is selected.

English often links a part to a whole with of, as in the end of the street. Body parts also commonly use a possessive form such as my hand, and some parts have names made from two nouns, such as table leg. One of names a member of a group, while half of and similar phrases name a portion.
The handle of the door is loose.
The part comes before of, and the whole comes after it.
One of my neighbors has a dog.
One selects a single member, but neighbors names the whole group and is plural.
I ate half of the apple.
Half of names a portion of one whole apple.
Learners whose language puts the whole before the part may reverse the order in an of phrase. Learners whose language uses a singular noun after a word meaning one of may write *one of my neighbor instead of one of my neighbors.
