Translation:I'm a student.
So when you don't say わたしは, is your being the subject just implied anyway since you're speaking?
Also, this might be a sentence put in after introducing the topic, yes?
As I understand it, in Japanese you continually introduce "topics" and they will remain the topic until you change them.
So for example, if you say.. わたしは田中です. (I'm Tanaka) then you don't have to include the わたしは again if you're still talking about yourself...it's implied.
I might be very wrong, so correct me if so!
No, you're absolutely correct! I will just say that, when you don't say わたしは, in this course you are implied as the subject because you're speaking. This isn't always the case when you're speaking in Japanese. As you pointed out, the topic could have previously been introduced as something else, so if you are still talking about that topic, you don't need to say it again.
Yes, the pronunciations vary sometimes depending how the kanji stands, whether it be alone or different kanji. For example: 誕生日 : tanjoubi (birthday) uses the same character 生 , but is pronounced different in comparison to 先生: sensei (teacher). Its really going to learn kanji apart from this and learning the meaning and where its used.
"a" is an indefinite article. This proceeds the noun to indicate a none specified now.
- a cat (over there).
- a dog (over there).
These show that there is none specific cat and dog. Where as "the", a definite article, shows a specific noun.
- the cat (over there).
- the dog (over there).
this specifies which cat or dog.
The first one has the subject specified and it can only be about "I" am student. The second one has the subject omitted, and thus it depends on who the subject understood for the sentence is. e.g. If the sentence is an answer for the question "Who are you?", then using the 2nd sentence is enough. The 1st sentence would still be used in some occasions, when the subject is not understood yet or to make an emphasis.
Can some one pleas help me, i dont understand why when duolingo wants me to translate from englush to japanese the correct answer for i am a student is 私は学生です but when its asking me.to rranslate a different japanese phrase (学生です) to english it ends up the same? What im asking in short is whats the difderence, formality? Can someone please explain?
Late reply, and you may have figured this out by now, but the difference between the two phrases you posted is the absence of 私は (Watashi wa) in the second phrase. Watashi wa would mean "I am" and omitting the subject ("I") is common. The subject (the speaker) is inferred in the second case. Both should be correct. I think in a more formal setting saying 私は is more polite.
Not at all, in Japanese the subject (so in this case "I") is often dropped if it can be easily assumed by the context of the sentence/conversation but it's not wrong to keep it in.
I'd avoid dropping subjects until you have a good grasp on using them, and then when you are pretty comfortable with them and have listened to a lot of Japanese and have sort of developed an ear for when to drop them try it out yourself because using them too much especially, "私は" can sound off to a native speaker's ear (think about how in English saying something like, "I have a dog. My dog is brown. My dog is cute. My dog is funny" sounds off or very childish too.
