I'm a little stuck... Click here to teach me more about this clue!

'eschew luxuries' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'one hosted by queen should' is the wordplay.
'one' becomes 'I' (Roman numeral).
'hosted by' indicates putting letters inside.
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'should' becomes 'ought' (synonyms).
'r'+'ought'='rought'
'i' inserted inside 'rought' is 'ROUGH IT'.

Can you help me to learn more?
