～をトライする ～を試してみる（ためしてみる） ~しようとする ～しようと試みる（こころみる） ～やってみる ～してみる ～を試す などなど

Hmm.. If you want to say you are trying to do an action, eg eating (たべます）, then you just put the verb into the Te-form and add みます on the end of it. so, for example, I am trying to eat ice cream アイスクリームをたべてみます。 It kinda means you want to try to see if you can do that action.

you'd like to know it in japanese? if so.. that "attempting to" is like "kokoromiru.." "試みる". and "I'm trying to tell a joke?" will be "jodan wo ittemiru." "ジョーダンを言ってみる". sorry if that's wrong answering.
