"With a green dress"
Translation:Mit einem grünen Kleid
If anyone else was confused by grünen vs grünem, this http://en.wikipedia.org/wiki/German_declension#Mixed_inflection.5B6.5D was helpful
Mixed declension is used when there is a preceding indefinite article (e.g. ein-, kein-), or possessive determiner (mein-, dein-, ihr-, etc.)
-------------| Ma | Fe | Ne | Pl
Nominative-| -e | -e | -es | -en
Accusative-| -en | -e | -es | -en
Dative------| -en | -en | -en | -en
*Not all adjectives.
Your rule only works for weak or mixed declension - when the noun has an article (or another word declined like an article)
When no article (or another word that gets declined like an article) is used then strong declension is applied.
Here -en, -em, and -er endings are possible for Dativ and Genetiv.
I put together my own page of compact charts to try to make it easier to memorize this.
Strong plural forms don't end in "en" (unless dative), - ie. if there is no article, then it follows strong adjective declension rules.
Predicate adjectives don't either - Adjectives that come after the noun don't get any ending at all.
Grüne Bananen sind grün.
Both of theses adjectives refer to a plural noun but neither ends in "en".
Apart from the modification of article in four cases (i.e. Nominative, Accusative, Dative, and Genitive), adjective in German must be changed depending on which case it is. "mit" is a preposition that is always followed by "dative case". Therefore "grünen", which is an adjective in dative form, must be followed by the -en ending..

I hope this will help :)
How do you know whether it is strong or weak? Is it because the quantity is clearly indicated by "einem?" (A single one, just in Dative.) I keep thinking you have to be able to tell the gender, but that's not true? It's knowing gender, OR case, OR quantity that would make it weak? Sorry if my question is messy. I'm having a brain dump moment.
