Once I heard the word "cast-off".. well, I'd like to use it instead of "scrap".
So, we have the sentence: "The delay was caused by some scrapped pieces"
Is it right to say "The delay was caused by some casted-off pieces" ??? Can I use this word as an adjective?
Not in that way- 'cast-off' is often used for clothes: he had to wear his elder brother's cast-offs.
