I was introduced to jisho.org a few days ago and I find it a really good tool to use while using the Heisig method to learn the readings as I learn the writing and understanding of kanji. I noticed 2 different symbols used when they present the kunyomi. So far I haven't seen them used in onyomi so I think they are not used in them. The "."(dot) and the "-"(dash). From what I gather I believe I got what they basically mean but please correct me if I'm wrong:
"." - the dot is used to show where the kanji stops and after it the following is written in kana. I think the trailing kana had a name but I really can't remember it now. Is this always the case? When I see a dot should I always assume it's only kana after it? Or can there be kanji as well in some compounds?
"-" - the dash is used to show that the word is allowed to form compounds only on the side where the dash is shown.
Take 一 for an example. Its 2 kun readings are: ひと-, ひと.つ so if I got this correctly:
一つ - this is how you write it according to the second reading.
Other thing I noticed is that there are times you can use a kanji instead of a trailing kana. I noticed this when I saw the other example compound on jisho 一月 Is this a common thing and does it have a term defining it so I can research further on my own?
一人 - this is really the only compound I could think of but the way I see it if the dash does what I think it does that means there will never be a compound word that has ひと somewhere elsewhere in the word apart from the beginning.
