What does blockable mean?
Blockable is a modern English adjective meaning capable of being blocked — that is, able to be obstructed, intercepted, or prevented from proceeding. It is formed by attaching the suffix -able to the verb block, and it appears most frequently in practical and technical contexts: emails that are blockable by spam filters, domains blockable by firewalls, calls blockable on smartphones, or shots in sport described as blockable by defenders. The word carries a neutral, matter-of-fact tone rather than any strong emotional charge, though it often implies that action can or should be taken to stop something undesirable. Its antonym, unblockable, describes the opposite quality. Because block itself has many senses — physical obstruction, communication cutoff, and prevention of movement — blockable inherits that flexibility, making it a useful term wherever something's vulnerability to obstruction is under discussion.

Etymology of blockable
Blockable derives from the verb block, which entered Middle English in the late medieval period from Old French bloquier, meaning to bar or obstruct, ultimately connected to the Germanic root behind 'bloc' — a solid mass of wood or stone. The suffix -able comes from Latin habilis via Old French, indicating capability. The combination follows the standard pattern of English denominal/verbal adjectives, and cognates sharing the block root include blockade, blockage, and bloc.
