Affordable → It is formed from "afford" (from Old English "forðian", meaning to provide or supply) and the suffix "-able" (meaning capable of being). The word "affordable" means capable of being provided or supplied at a cost that is reasonable or manageable.
Think of being able to 'provide' something ('afford') and that it is 'capable' ('-able') of being within your budget. This helps you remember that 'affordable' means something you can manage to pay for.
