Typical of those doing nothing in one train out around Spain (7)
I believe the answer is:
inertia
'typical of those doing nothing' is the definition.
I can't judge whether this defines the answer.
'one train out around spain' is the wordplay.
'one' becomes 'i' (Roman numeral).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'around' is an insertion indicator.
'spain' becomes 'e' (abbreviation for Espana).
'train' anagrammed gives 'nrtia'.
'nrtia' going around 'e' is 'nertia'.
'i'+'nertia'='INERTIA'
'in' is the link.
Can you help me to learn more?
(Other definitions for inertia that I've seen before include "Unwillingness to move" , "Idling" , "Listlessness" , "Idleness" , "'Sluggishness, indolence (7)'" .)
