Danke für die Ergänzung, aber hier noch eine Ergänzung zur Ergänzung:

Relative Pronouns
The relative pronouns (
who/whoever/which/that) relate groups of words to nouns or other pronouns (The student
who studies hardest usually does the best.). The word
who connects or relates the subject,
student, to the verb within the dependent clause (
studies). Choosing correctly between
which and
that and between
who and
whom leads to what are probably the most Frequently Asked Questions about English grammar. For help with
which/that, refer to the
Notorious Confusables article on those words (including the hyperlink to Michael Quinion's article on this usage and the links to relevant quizzes). Generally, we use "which" to introduce clauses that are parenthetical in nature (i.e., that can be removed from the sentence without changing the essential meaning of the sentence). For that reason, a "which clause" is often set off with a comma or a pair of commas. "That clauses," on the other hand, are usually deemed indispensable for the meaning of a sentence and are not set off with commas. The pronoun
which refers to things;
who (and its forms) refers to people;
that usually refers to things, but it can also refer to people in a general kind of way. For help with
who/whom refer to the section on
Consistency. We also recommend that you take the quizzes on the use of
who and
whom at the end of that section.
The expanded form of the relative pronouns —
whoever, whomever, whatever — are known as
indefinite relative pronouns. A couple of sample sentences should suffice to demonstrate why they are called "indefinite":
- The coach will select whomever he pleases.
- He seemed to say whatever came to mind.
- Whoever crosses this line first will win the race.
What is often an
indefinite relative pronoun !!!!:
- She will tell you what you need to know.
Indefinite Pronouns
The indefinite pronouns (everybody/anybody/somebody/all/each/every/some/none/one) do not substitute for specific nouns but function themselves as nouns (
Everyone is wondering if
any is left.)
One of the chief difficulties we have with the indefinite pronouns lies in the fact that "everybody" feels as though it refers to more than one person, but it takes a singular verb. (Everybody
is accounted for.) If you think of this word as meaning "every single body," the confusion usually disappears. The indefinite pronoun
none can be either singular or plural, depending on its context.
None is nearly always plural (meaning "not any") except when something else in the sentence makes us regard it as a singular (meaning "not one"), as in "None of the food is fresh."
Some can be singular or plural depending on whether it refers to something countable or noncountable. Refer to the section on
Pronoun Consistency for help on determining the number of the indefinite pronouns (and the number [singular/plural] of the verbs that accompany them). There is a separate section on the uses of the pronoun
one.
There are other indefinite pronouns, words that double as
Determiners:
[blockquote]enough, few, fewer, less, little, many, much, several, more, most, all, both, every, each, any, either, neither, none, some[/blockquote]
- Few will be chosen; fewer will finish.
- Little is expected.
See the section on
Pronoun Consistency for help in determining the number (singular/plural) characteristics of these pronouns.
Nur, damit alles seine Richtigkeit hat... Ich frage mich allerdings ein wenig, ob eine solche Ausführlichkeit in einem Fall wie obigen wirklich sehr sinnvoll ist. Wenn ein User erstmal nur nach dem Unterschied von "what" und "that" in einem Relativsatz fragt, den er selbst vielleicht noch nicht einmal als solchen identifiziert hat, kann die Antwort vielleicht ruhig etwas weniger kompliziert ausfallen. Aber OK, das ist Geschmackssache. Ich gehe hier im Forum vielleicht weniger von der Wissensschaftsseite an Probleme heran als vielmehr von der "Erklärenwollenundhoffendassdiefragendenauchetwasmitderantwortanfangenkönnen"-Seite.
No offence!
