1. Could someone please explain the Middle Voice?
2. Is there a dictionary somewhere out there online that marks strong/weak nouns, gender, and maybe even irregularities?
1) The middle voice is a verb form in Icelandic that is easily distinguished by its -st endings. In principle, the middle voice is formed by adding -st to the infinitive of conjugated verb formsm, as appropriate, with the following changes.
-Second and third endings -(u)r, -ð, and -rð are deleted.
-Dentals (ð, d, t) are deleted before middle voice -st where deleted also in pronunciation.
fá - fást = to get, to obtain.
fæ - fæst
færð - fæst
fær - fæst
fáum - fáumst
fáið - fáist
fá - fást
The middle voice is used to express the followingÆ
The middle voice can replace a reflexive pronoun, as in...
Barnið meiður sig --- Barnið meiðist
The child hurts itself.
Note, however, that not all reflexive constructions can be replaced by a middle voice.
The middle voice can add the meaning of "each other" to a main verb.
Kjartan talar við Sif og Sif talar við Kjartan --- Kjartan og Sif talast við
Kjartan and Sif talk to each other.
We'll see each other again!
-Separate meaning or only existing or only exisiting form of the verb. The middle voice can give a verb a different meaning...
koma vs. komast --- to come vs. to get there
taka vs. takast --- to take vs. to work, to succeed
gera vs. gerast --- to do vs. to happen
2) Unfortunely I do not know a dictionary that will do such thin. Sorry!
