Disinclination to move hotel supporting small fortune (5)
I believe the answer is:
sloth
'disinclination to move' is the definition.
I can't judge whether this definition defines the answer.
'hotel supporting small fortune' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'small' becomes 's' (abbreviation - e.g. clothes size).
'fortune' becomes 'lot' (as in a person's lot in life).
's'+'lot'='slot'
'h' put after 'slot' is 'SLOTH'.
Can you help me to learn more?
(Other definitions for sloth that I've seen before include "tropical American native" , "Sinful" , "Deadly sin - upside-down mammal" , "One's often suspended from tree" , "one of a deadly collection" .)
