Frequently Asked Questions

Yes, but usually in the context of refining skills or abilities (e.g., 'fine-tune your public speaking skills'), not for adjusting the person themselves.
'Tweak' is more informal and can imply a quick, minor adjustment, often by trial and error. 'Fine-tune' suggests a more systematic, precise, and often expert adjustment aimed at optimisation.
The direct noun is 'fine-tuning' (e.g., 'The fine-tuning of the engine took hours'). The process or result can also be called a 'fine adjustment' or 'calibration'.
