Capable of being associated or connected with something; able to be related or joined together in thought or fact.
From Latin 'associare' (to associate, from ad- 'to' + socius 'companion') plus the suffix -able (from Latin -abilis), meaning 'capable of being.'
The -able suffix is one of English's most powerful tools—add it to almost any verb (walk→walkable, like→likable, think→thinkable) and you get an adjective, making English endlessly creative!
