Conventional way of reaching country home kept by the French? (4-4)

'conventional way of' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'country home kept by the french?' is the wordplay.
'country' becomes 'land' (synonyms).
'home' becomes 'in' ('he's home' can mean 'he's in').
'kept by' indicates putting letters inside.
'the french?' becomes 'le' ('the' in French).
'in' going inside 'le' is 'line'.
'land'+'line'='LAND-LINE'

'reaching' acts as a link.

Can you help me to learn more?
