Sense: adjective/1
All four words describe something a person can get hold of, but they differ in tone and focus. 'Available' is the everyday choice and works for products, services, information, and people. 'Obtainable' is more formal and often hints that some effort is needed: 'These rare coins are obtainable only through specialist dealers.' 'Accessible' shifts the focus to ease of reaching or using something, especially places, websites, or services for people with disabilities: 'The museum is fully accessible by wheelchair.' 'On offer' is informal and common in shops or ads, suggesting something is being actively presented for sale: 'A wide range of desserts is on offer at the café today.' When in doubt, 'available' is the safest neutral pick.

Etymology
'Available' came into English in the late 1400s, formed from 'avail' (meaning 'to be of use' or 'to help') plus the suffix '-able' (meaning 'capable of'). 'Avail' itself traces back through Old French to the Latin verb 'valere', which meant 'to be strong' or 'to be worth something'. The earliest meaning was closer to 'effective' or 'valid', as in a legal document. The modern senses — 'able to be obtained' and 'free to meet' — only became common in the 1800s.
