Anyone can explain the term - "reduced clause", thanks.
I think it is a clause from which certain words are ommitted to save space, or because it is easy enough to understand the meaning of the clause without them.

For example;

Pick the fruit 'when ripe'. 'when it is ripe'

Let me know 'as soon as possible'. 'as soon as it is possible'

'Although confident' of victory, we knew it would not be easy. 'although we were confident'

Thank you. I get the pointEmotion: big smile
