Simplifying "I know that you like me" style sentences.

I'm trying to figure out the best way to approach subject and topic on a sentence like "I know (that) you like (me)" without being too verbose.

I figured the best way to phrase this particular sentence is:
"私はあなたが私を大好き知っている" but this seems very verbose. Is the best way to simplify it to drop the initial "watashi wa"? Or would this confuse the end result of WHO knows that you like ME?

I'm fairly new to japanese but learn quickly. I've grabbed a few japanese children's books on my new amazon kindle e-reader and am using that to figure out more colloquial and lengthy sentence patterns and grammar. (one of which is a japanese translation of "slightly eaten pie" which has some interesting vocabulary, sentences, and furigana!

Thanks in advance.

In a conversation, usually it's obvious you are talking to the addresse about the topic "whom he/she likes", so you don't need to mention even the subject of 好き. Furthermore, sentence final particles can be used to fix the direction of love/like.
e.g.
僕のこと好きだって知ってるよ。 / あたしのこと好きだって知ってるのよ。
僕を好きなことくらいわかるよ。 / 私を好きなことくらいわかるわよ。
僕のこと好きなんだろ？ / あたしのこと好きなんでしょ？

As for a written sentence "I know he likes her", 私は彼が彼女を好きだと知っている would be common.

Thank you so much! I'm rather new and not sure of how to properly use the "koto" placeholder noun yet. Can you offer an explanation as to the grammatical reasoning for its usage here, and other reasons/places to use it? I assume the two examples are just assuming the gender of the speaker/one who is liked (boku vs atashi/watashi). Also assume that "datte" is used to chain the two verbs of suki & shiteru, am I correct?

I was thinking on this sentence construction this morning more, and another example I was wondering about was "if/do you still want my opinion/input on your english" .

I think this is just something someone new at japanese overthinks due to the omission of subjects being commonplace, and trying to figure out if the other person in question would be a subject, or an object, or a topic! (I haven't had formal english grammar classes either, I was a high school dropout - makes it much more confusing.)

If you are referring to "nominalizer", I already explained it in this forum, but the post displays full of mojibake due to the recent conversion, as written at the top of this page.

It depends on the type of the verb in the main clause which nominalizer should be used.

1)verbs basically used with こと
verbs regarding thoughts, communication/affection with words
言う、話す、伝える、教える、知らせる、命令する、要求する、考える、思う、信じる、、、

彼女が出て行ったことを彼に話した。

This こと is often interchangeable with と for quotation.

彼女が出て行ったと彼に話した。


2)verbs basically used with の
sensory/perceptive verbs, verbs which express that an action/movement comes into effect at the scene, at the time.
見る、見える、聞く、聞こえる、感じる、手伝う、助ける、とめる、待つ、、、

This の can be interchangeable with the nominalizer ところ in some cases.

彼女が部屋を出て行くのを見た。
彼女が部屋を出て行くところを見た。(This sentence is correct, but the meaning is changed from の.)

もの is used only as a pronoun.

って is a colloquial form of the quotaion と. The -te form of copula is で, not だって.

Are you using textbooks or something? Have you learned conditional clause?
