Would appreciate the parsing explained for these:-
A trainee appears in goal mostly for free - AT LARGE (Free)
Old man's gaining energy with each swim here in ME - DEAD SEA I see DAD with E Energy but where does the SEA come from?
Sign under this is not mine - YOURS? Where do any of the letters come from?
Plastic discs control a quiet vehicle - CASH CARDS I see SH Quiet CAR Vehicle but the rest...?
