I have learnt that one of the uses of the word "doch" is that it can be used to invert a negative statement. For instance:
Hast du kein Geld?
We can reply:
Doch! Ich habe Geld.
Or:
Du hast das nicht gemacht?
Response:
Doch! Ich habe das gemacht.
However, does the initial negative statement have to include "kein" or "nicht" to specifically indicate a negative statement? Or can "doch" be used to respond to negative statements that are implied?
E.g.
Bist du knapp an Geld?
Could we respond with "Doch, Ich habe viel Geld"?
Englisch finde ich sehr schwierig. Deutsch is einfacher.
Could we respond with "Doch, English ist einfacher!"?
