Part and whole
What is it a part or member of?
Meaning
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.
How to spot it
Look for something presented as a piece, member, or portion of a larger thing, group, or amount.
In your native language
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.
In your learning language
Spanish usually links a part to its whole with de after the word for the part. A number or a word such as uno or algunos followed by de selects members from a group. Words for pieces or portions use the same pattern, as in un trozo de pan.
Una pata de la mesa está rota.
One leg of the table is broken.
Dos de mis amigos viven cerca.
Two of my friends live nearby.
De selects two members from the group of the speaker's friends.
¿Quieres un trozo de pan?
Would you like a piece of bread?
Learners whose language puts the whole before the part may reverse the Spanish order or omit de. Learners whose language does not distinguish a number of items from members selected from a group may confuse dos amigos with dos de mis amigos.
