What's the difference between apposition and parenthesis?

It is a very fine distinction, but as far as I understand it apposition places two concepts together by way of helpful and constructive explanation, while parenthesis is an incidental statement at what might be termed a further remove.

My brother, the police inspector, is receiving a decoration.

(Apposition, as it is identifying the brother concerned and suggesting why he is being decorated.)

My brother, who had recently arrived from Brazil, was with me on that occasion.

(Parenthesis, as the fact that my brother had recently arrived from Brazil is not strictly relevant to what I am saying.)

My sister, who is a brilliant cook, is taking charge of the catering.

(Apposition, as the fact that my sister is a brilliant cook explains why she is in charge of the catering.)

My aunt, who has never liked travel, nevertheless agreed to accompany us.

(Parenthesis, as the fact that she has never liked travel does not explain why she agreed to accompany us.)

Even though you ahve your answers I can, nevertheless, give you mine XD

Parenthesis: Either or both of the upright curved lines, ( ), used to mark off explanatory or qualifying remarks in writing or printing or enclose a sum, product, or other expression considered or treated as a collective entity in a mathematical operation.

1. (Linguistics / Grammar) a phrase, often explanatory or qualifying, inserted into a passage with which it is not grammatically connected, and marked off by brackets, dashes, etc.

(Linguistics / Grammar)

in parenthesis inserted as a parenthesis

[via Late Latin from Greek: something placed in besides, from parentithenai, from para-1 + en-2 + tithenai to put]

Apposition:

1. Grammar

a. A construction in which a noun or noun phrase is placed with another as an explanatory equivalent, both having the same syntactic relation to the other elements in the sentence; for example, Copley and the painter in The painter Copley was born in Boston.

Middle English apposicioun, from Latin appositi, appositin-, from appositus, past participle of appnere, to put near;

2. (Linguistics / Grammar) a grammatical construction in which a word, esp a noun phrase, is placed after another to modify its meaning

Hope you find it useful. Mind you, this is almost the same as in Spanish. The use of parenthesis may vary in the way many Spnish speakers use it to write side comments but essentially it is the same.

Parenthesis: An expression that amplifies or explains a passage. It is usually set off by parentheses.

Apposition: The placing of two nouns, or their equivalents, that refer to the same thing or person next to each other without being joined by a conjunction construction. Ex: "My brother Brad" rather than "My brother, whose name is Brad". The word can also refer the relation of pair of nouns or their equivalents.

Appositin

Parenthesis is a sentence within another sentence, marked by commas, dashes or brackets ( ).

Apposition is the addition of one word or group of words to another as an explanation.

Example: Mrs White, our new teacher, is a German. Here "Mrs White" is in apposition to "teacher".
