For example.. "I love _____", do I write "_____um amo."? (since -um is the accusative singular masculine ending? and then -am if the noun is singular feminine?)

Hope you understand my question. >< Thanks.
LATIN! Not Spanish nor other languages spoken in Latin America~

I need to know about how to write a superlative in >>Latin<<. I have a report and i can't find anything about it on the web. I have to explain what it is and give a presentation by making a game of "Is It or Is it Not a Superlative?".
