How to translate the construction "noun + で"

Question

When going over a summary of Japanese grammar I came across the following sentence:

私は学生で友だちはいしゃです。

How should this be translated? It supposedly covers the construct of noun+で. Is it the te-form?

Answer 1

”で” Here is the te-form of the coupla "だ/です" and means simply "is", but it has the connotation of continuing on with the sentence, instead of ending it like "だ" would.

So "AはBで。。。" would mean "A is B and..."

Answer 2

Both nouns(名詞) and na-adjectives(形容動詞) have the same continuative-form(連用形) which is the form you use in a sentence to keep it going, and consist in appending で to them at the end.

• [彼女]{かのじょ}　は　[静]{しず}かで　18[歳]{さい}で　[美人]{びじん}です 。
• She's quiet, 18 years old and a beauty.

In the example above we chained a na-adjectve followed by a noun(years) – also chained – and finished with another adjective.
