The most common method is derivation, which involves adding affixes like prefixes and suffixes to words. Other methods include loan-word, calque, compounding, blending, clipping, hypocorism, and back-formation. For example, the word "unhappiness" is formed by adding the prefix "un-" to the word "happiness".
