'・と' for adjectives + verbs? how is this?
In another question someone asked what's the word for 'slow'. I knew it was yukkuri, but searched anyway, and saw it's a '-na' form adjective, so i thought about writing an example like that... but when i saw the examples on the dictionary, none use the '-na' form, but some use '-to'. How is that?
In the pimsleur's lessons i'm taking, when they wanna say 'adjective + verb', they don't use any word inbetween, for example
ゆっくり話します. yukkuri hanashimasu
but on the examples from the dictionary, all seem to add 'to' inbetween:
彼はゆっくりと歩く.
私はドアをゆっくりと開けた.
1. what's the right way to do it? conversationally, which one do you use?
2. also.. what about the '-na' form? is it only for saying something like 'a slow [noun]' ? 'ゆっくりな車' ?
thanks in advance!
