Sorted
What it really means
Arranged, fixed, dealt with. "It's all sorted" means everything is organised. Also said alone as a reply: "Sorted!" = done, no problem.
Context, tips & common mistakes
Sorted is the all-purpose word for 'fixed, arranged, dealt with': the visa is sorted, the flat is sorted, 'I've sorted it with the landlord.' As a one-word reply — 'I booked the tickets.' 'Sorted!' — it closes loops with satisfying finality, and 'get it sorted' is the standard instruction to fix something, from bosses and flatmates alike.
Applied to a person, 'he's sorted' means his affairs are in order — job, flat, life admin under control — quiet praise in a culture that rates competence. For newcomers it is also a genuinely useful verb for bureaucracy: 'I need to sort my National Insurance number' communicates the entire mission. Informal but universal; only formal writing needs 'arranged' or 'resolved'.
