 (wĭch, hwĭch)
1. What particular one or ones: Which of these is yours?
2. The one or ones previously mentioned or implied, specifically:
a. Used as a relative pronoun in a clause that provides additional information about the antecedent: my house, which is small and old.
b. Used as a relative pronoun preceded by that or a preposition in a clause that defines or restricts the antecedent: that which he needed; the subject on which she spoke.
c. Used instead of that as a relative pronoun in a clause that defines or restricts the antecedent: The movie which was shown later was better.
3. Any of the things, events, or people designated or implied; whichever: Choose which you like best.
4. A thing or circumstance that: He left early, which was wise.
1. What particular one or ones of a number of things or people: Which part of town do you mean?

[Middle English, from Old English hwilc; see kwo- in Indo-European roots.]
Usage Note: The relative pronoun which can sometimes refer to a clause or sentence, as opposed to a noun phrase: She ignored him, which proved to be unwise. They swept the council elections, which could never have happened under the old rules. More than 80 percent of the Usage Panel approved both of these examples in our 2009 survey. Sometimes which clauses of this sort are presented as separate sentences. These are technically sentence fragments, and they often pack a rhetorical punch: "I was caught for a week on the Siachen Glacier, in a giant blizzard. There is no harsher place on this earth; it belongs to no one. Which won't keep people from squabbling over it someday" (Andrea Barrett). While this example is perfectly acceptable, writers who want to avoid this use of which and adhere to the traditional rules can usually substitute this for it at the start of a new sentence, though often at the loss of some dramatic flair. · Note that which clauses that modify whole sentences can sometimes create ambiguities. The sentence It emerged that Martha made the complaint, which surprised everybody may mean either that the complaint itself was surprising or that it was surprising that Martha made it. This ambiguity may be avoided by using other constructions such as It emerged that Martha made the complaint, a revelation that surprised everybody. Remember that which is used in this way only when the clause or sentence it refers to precedes it. When the clause or sentence follows, writers must use what, particularly in formal style: Still, he has not said he will withdraw, which is more surprising. Still, what is more surprising, he has not said he will withdraw. See Usage Notes at that, what, whose.

usage: The relative pronoun which refers to inanimate things and to animals: The house, which we had seen only from a distance, impressed us even more as we approached. The horses which pulled the coach were bay geldings. Formerly, which referred to persons, but this use, while still heard (the friend which helped me move), is now nonstandard. The “rule” taught by some usage guides, that which should be used only with nonrestrictive clauses, has not taken hold generally. In edited prose a majority of the clauses in which which is the relative pronoun are restrictive: Facts which we had ignored turned out to be critical. See also that.

Which can be a determiner or a pronoun.

1. asking for information

You use which when you are asking for information about one of a limited number of things or people. A noun phrase beginning with which or consisting of the pronoun which can be the subject, object, or complement of a verb. It can also be the object of a preposition.

Which type of oil is best?
Which is her room?

Be Careful!
When the noun phrase is the object of a verb or preposition, you put an auxiliary verb after the object, followed by the subject and the main verb. When the noun phrase is the object of a preposition, the preposition usually goes at the end of the clause.

Which hotel did you want?
Which station did you come from?
2. used in reported clauses

Which is often used in reported clauses.

Do you remember which country he played for?
I don't know which to believe.
3. used in relative clauses

Which can be a relative pronoun in both defining and non-defining relative clauses. In relative clauses, which always refers to things, never to people.

We heard about the awful conditions which exist in some prisons.
I'm teaching at the local college, which is just over the road.

In relative clauses, you can use either which or who after a collective noun such as family, committee, or group. After which you use a singular verb. After who you usually use a plural verb.

He is on the committee which makes decisions about planning.
They are a separate ethnic group who have their own language.

Be Careful!
When which is the subject of a non-defining clause, don't use another pronoun after it. Don't say, for example, 'He stared at the painting, which it was completely ruined'. You say 'He stared at the painting, which was completely ruined'.

1. (in direct and indirect questions, reported speech)
Which/which one/which ones in direct and indirect questions and after expressions of (un)certainty and doubt (e.g. no sé) usually translate as cuál/cuáles:
which do you want? (offering one) → ¿cuál quieres?; (offering two or more) → ¿cuáles quieres?

which of you did it?¿cuál de vosotros lo hizo?
which of you is Kathleen?¿cuál de vosotras es Kathleen?

I don't mind whichno me importa cuál
2. (relative)
2.1. (replacing noun)
In relative clauses where which defines the noun it refers to, you can usually translate it as que. Note that in this type of sentence which can be substituted by that in English:
the letter which came this morning was from my niecela carta que llegó esta mañana era de mi sobrina
it's an illness which causes nerve damagees una enfermedad que daña los nervios
do you remember the house which we saw last week?¿te acuerdas de la casa que vimos la semana pasada?
the bear which I sawel oso que vi
If which is the object of a preposition, you can either translate it as que (usually preceded by the definite article) or as ARTICLE + cual/cuales. Use the second option particularly in formal language or after long prepositions or prepositional phrases:
your letter, which I received this morning, cheered me uptu carta, que or (more frm) la cual he recibido esta mañana, me ha levantado el ánimo
the bull which I'm talking aboutel toro del que or (more frm) del cual estoy hablando
the meeting which we attendedla reunión a la que or (more frm) a la cual asistimos

the cities to which we are goinglas ciudades a las que or (more frm) a las cuales vamos
he explained the means by which we could achieve our objectiveexplicó los medios a través de los cuales podíamos alcanzar nuestro objetivo
If instead of defining the noun the which clause merely adds additional information, you can translate which using either que or ARTICLE + cual/cuales:
the oak dining-table, which was a present from my father, seats 10 people comfortablyla mesa de roble, que or la cual fue un regalo de mi padre, admite cómodamente diez comensales
2.2. (replacing clause)
When which refers to the whole of a preceding sentence or idea, translate as lo que or lo cual:
it rained hard which upset herllovió mucho, lo que or lo cual le disgustó
they left early, which my wife did not like at allse marcharon pronto, lo cual or lo que no agradó nada a mi mujer
After a preposition only lo cual can be used:

after which we went to beddespués de lo cual nos acostamos
from which we deduce thatde lo cual deducimos que ...
1. (in direct and indirect questions, reported speech)
When which is used as an interrogative adjective, translate using qué + NOUN when the possibilities are very open or cuál/cuáles de + ARTICLE + PLURAL NOUN when the possibilities are limited:
which house do you live in?¿en qué casa vives?
which day are they coming?¿qué día vienen?
I don't know which tie he wantsno sé qué corbata quiere
which picture do you prefer?¿qué cuadro prefieres?, ¿cuál de los cuadros prefieres?
which option do you prefer?¿cuál de las alternativas prefieres?
which way did she go?¿por dónde se fue?
