Loosing? Learn the English language, people!

I wouldn't call the distinction 'slight'.

Current usage is slipping into things like:

'He rents the flat to his brother.' (wrong)
'He rented out the flat.' (correct but clunky)

He rents it from himself
He lets it to himself
He rents it to himself
? He lets it from himself ?

All correct except for the last one.
