Out of practice — starts to read up suitable texts? Yes (5)
I believe the answer is:
rusty
'out of practice' is the definition.
(I've seen this before)
'starts to read up suitable texts? yes' is the wordplay.
'starts to' indicates taking the first letters.
'yes' becomes 'y'.
The first letters of 'read up suitable texts' is 'rust'.
'rust'+'y'='RUSTY'
(Other definitions for rusty that I've seen before include "(Of iron) affected by damp" , "(Of knowledge) not current" , "a bit faded" , "Stiff with age" , "Having a reddish-orange oxide coating" .)
