2. Word formation
Both inflectional (or grammatical) e.g. plural suffix, genitive suffix, present or past participle etc. and derivational (or lexical) affixes e.g.un-, mis-, -ness, -ship, -hood are attached to roots.
Another kind of word formation is where more than one root is joined together (e.g. baby-sit). This is called compounding.
Conversion word formation is when a change of word class occurs without any affixation (e.g. skin, a verb derived from a noun, or input, a noun derived from a verb)
