Sense: adjective/1
'Trusty', 'reliable', 'dependable', and 'trustworthy' all describe something or someone you can count on, but they differ in scope and connotation. 'Trusty' is the most limited of the four — it is almost always used before a noun, has a slightly old-fashioned or affectionate tone, and strongly implies long-term personal experience with an object ('his trusty old bicycle'). 'Reliable' is the broadest and most neutral term, working for both people and things in any register ('a reliable car', 'a reliable colleague'). 'Dependable' is very close to 'reliable' but leans slightly more toward personal character ('a dependable friend who never cancels'). 'Trustworthy' focuses specifically on honesty and moral integrity ('a trustworthy accountant who handles company funds'). You can say a person is trustworthy but rarely trusty; you can say a tool is trusty but it sounds odd to call it trustworthy. For everyday use, 'reliable' or 'dependable' are the safest choices.
Etymology
Trusty comes from the Middle English word 'tristi', formed from 'trust' (confidence in someone or something) plus the adjective suffix '-y'. The noun sense — a prisoner considered trustworthy enough to receive special privileges — developed in 19th-century American English within the prison system.
