I am a little unclear as to what the definition of Indirect Speech is especially as it applies to the examples given in the lesson and in the use of verbs such as, 'se demander' and 'savoir'.
How is this Indirect Speech:
Je me demande si tu viens ou pas. ?
What I do understand is that in cases where 'whether = if', then 'si + Mode Indicatif' is applied.
The way I usually work it out in my mind is if the sentence is expressing the idea of 'regardless of which' or 'whether or not' than 'Que + Le Subjunctif' is used.
